Twins week 11 and 12
12 week old twins

If you've felt like every day seems like the movie Groundhog Day and you've been worried that it will never get better — guess what! Right about now you may notice that it starts getting better! Longer stretches between feedings will be a game-changer and your babies will soon interact more with you. Savor every single milestone, no matter how small, and write them down or you will forget them. Sending yourself quick emails is an easy, low-stress way to record everything. Qeepsake and Tinybeans are great apps for recording and sharing milestones.

What to Expect with Twins Week 11 and 12

  • Now is a good time to start putting your babies to sleep “drowsy, but awake”. Lay them to bed on their backs while still awake and leave the room. This will help them start to learn how to self soothe. They will probably cry and want to be picked back up, which is OK — you should do that, then settle them down and try again. Just keep trying and don't feel defeated if it doesn't work for a while. Practice is what we're looking for right now.
  • You'll start to notice your twins' hand-eye coordination developing fast
  • Practice tummy time during the daylight hours. Your goal is to get to 60 minutes of tummy time a day by 3 months old. Break this down into a few times a day after feedings. Read more about tummy time here
  • Keep your babies on a blanket or play mat on the floor as much as possible during the day. Put toys and baby mirrors around them to encourage them to reach out and begin to move.
  • Try to limit using baby containers (bouncy chairs, swings, etc.) for no more than 30 minutes at a time. Learn more about container baby syndrome here.
  • Carrying your twins so they can look over your should encourages them to lift their heads and look around. You will likely have to do this one baby at a time but eventually they will get really good at it and you can try to carry both at once. Tandem baby carriers are great for this and they also let you get more things done around the house.
  • Your twins will by now be putting their fingers into their mouths and trying to grasp objects and bring them to their mouths. Be extra careful about what you leave out within the twins' reach. Anything that can fit through a toilet paper roll can get lodged in your baby's throat.
  • You'll start noticing your babies going through fewer diapers. But you'll still be buying a LOT of diapers. Expect to go through 100-125 diapers per week for twins through Week 16. Here's where you can stock up: buy on Amazon.
  • You'll be doing 6 – 8 feedings a day (every 3 – 4 hours). Make sure you're feeding your babies at the same time and putting them down to sleep at the same time to keep them together on a schedule. Learn about bottle-feeding here
  • Babies are eating typically 4 – 6 oz at each feed in weeks 11 and 12, but if your babies are preemies they may be eating less. Ask your pediatrician what is the appropriate amount for your babies based on their weights.
  • You can expect your twins to gain around 6-8 oz each week now. They need sleep in order to grow. Research shows that 80% of growth hormone is secreted during slumber.
  • Start practicing good hygiene to prevent illness but don't go overboard with the anti-bacterial wipes. Some contact with germs in important for your twins. Baby's immune system will not be given the opportunity to develop properly without having things to fight. Aim to keep things “clean” rather than “sterile”. This will ensure your home is safe from harmful germs yet suitable to allow their immune systems to develop properly.
  • Your twins are fascinated by everything that's going on around them, and attracting their attention while feeding and changing may be difficult. If feedings are taking too long, move to a quiet room with fewer distractions.
  • If one or both twins are suffering from diarrhea or being fussy at feedings, it's possible they have an allergy to their formula or to something you're eating (if you're breastfeeding). Talk to your doctor about this. They may be able to prescribe a special formula (which may be covered by insurance.)
  • Now is a good time to start a bedtime routine. A bath, a book, a feeding, a lullaby, and down to sleep is a great routine. This pattern will cue your babies to learn that “bedtime” is starting. Do the same thing every night and they'll start to catch on to your cues. Learn more about bedtime routines here.
  • Babies' skin is thinner, more sensitive, and less oily than adults' skin which makes it prone to drying out. If your babies' skin is dry, try not to bathe them too often (every 3-4 days is fine) and avoid using soap or bubble bath. Plain warm water or a drop of hypoallergenic baby bath is enough.
  • Your babies should be placed to sleep on their backs on a firm, flat surface with only a tightly-fitted crib sheet. No blanket, no toys, no bumpers, no flat sheets. You baby should wear a swaddle blanket or wearable blanket for warmth and comfort. Do not sleep your babies on an inclined surface (learn why here). Following these recommendations will greatly reduce the risk of SIDS and accidental suffocation. Learn more about SIDS here.
  • Dress your twins in a swaddle blanket for sleep, which will keep them warm and safe in the crib while providing the comfort and security of the swaddle. Once they start rolling you'll transition to sleep sacks. Learn more about swaddling here
  • The American Academy of Pediatrics (AAP) recommends babies get doctor checkups at birth, 3 to 5 days after birth and then at 1, 2, 4, 6, 9, 12, 15, 18 and 24 months. Reminder that twins = two co-pays for each doctor’s visit.
  • If you haven't already tried pacifiers and your twins are screaming their heads off, now is a great time to start! Pacifiers are a lifesaver for parents of twins because we can't keep everyone happy all the time. Someone will always have to wait and a pacifier can help keep your waiting baby calm. Read about pacifiers here.
  • Have you started leaving the house at least once a day with your twins? If not, make it a goal for this week. You don't have to go far — around the block is enough. This will do wonders for your mental state! Learn about getting out of the house with twins here
  • If you haven't already started, now is the time to start baby proofing! Once your twins start crawling you will thank us! You'll want to baby proof every room in your house but each room will need a different variety of babyproofing tools. If you're not a handy person you may want to hire a professional babyproofer to come in and set you up. Read about making your home more safe here.
  • Are you going back to work soon? If you need to hire a nanny, we recommend giving yourself 2 months lead time. Read about doing a nanny search here.
  • At this point, if you're feeling anxious or depressed on a daily basis, you may be suffering from postpartum depression or anxiety. These conditions are more common with moms of twins and you have nothing to be ashamed of. Take it from us — we have been there!! Call you doctor or therapist and make an appointment to be seen. There are psychologists that specialize in postpartum mood disorders — call your medical insurance and ask for a list of providers in your network.
  • You are likely feeling exhausted, downtrodden, and though your body has taken a beating. This is very common with new twin moms. Try to be realistic about getting back to your “pre-babies body”. We recommend taking things slow and giving your body a full year to find it's new “normal”. That doesn't mean you can't eat healthy and exercise (once you have your doctor's blessing). But if you're having a hard time finding the motivation to do so, it's because you JUST HAD TWINS. Give yourself an extra helping of grace and be patient. You will get there. Just not as quickly as your friends who had one baby at a time.
  • If you feel like your pelvic floor is “falling out” give your doctor a call. This isn't very common but you may be suffering from uterine prolapse. Read about uterine prolapse here.
  • If you feel like you still look pregnant, it could be diastasis recti, which is common with twin pregnancies. Read about diastasic recti here.
  • If you haven't already, look into joining a local moms of multiples club (aka twin club). Read about local twin clubs here

Common concerns from the moms who have been there with twins week 11 and 12

Milestones & developmental leaps parents have noticed with twins week 11 and 12

What’s going on with development in twins week 11 and 12?

  • Your twins may be smiling and giggling with a greater frequency this week as they become more aware and curious of their surroundings.
  • Your twins may begin to roll from front to back this week, but many babies don't start this until around 4 months old. When you notice they are starting to roll you should transition them out of a swaddle and into a sleep sack (this one is great for transitioning)
  • Your babies body movements are becoming smotther and seemigly more purposeful as they gain more control over their muslces.
  • This is the age when many infants begin to recognize repetition. Change it up to keep them entertained.
  • Your twins may be able to sleep for longer stretches at night. You could be getting up to 6 hours of consecutive sleep a night! Check with your pediatrician to see if you need to stick to a strict feeding schedule overnight or if you can wait until one baby wakes up to start the next feeding. It may be too soon to start doing this if your babies don't yet weigh enough (but keep asking.)
  • You may see your twins bringing their hands and feet to their mouth often. They are just realizing they can do this.
  • You babies may begin to interact with their toys more this week. They are finally noticing them and their curiosity is running wild. They will likely swipe and kick at their toys.
  • Your twins are not ready for sleep training. Please don't try this before 12 weeks old.
  • You may notice your twins mouthing as if they are speaking when you are speaking to them. They are trying to mimic your movements to practice.
  • Your babies will start to mimic your facial expressions.
  • Your twins will begin grasping objects and maybe even your hands and clothes.
  • Your twins will feel objects in their hands without always grabbing them.
  • You may see (and hear) your twins attempting to mimic sounds you are making at them or making cooing noises, as if they are practicing communication skills. Talk to them often so they can practice.
  • Your twins curiosity has them demanding to sit up and look around more often this week.
  • Your babies may start to notice each other. It's a common misconception that newborn twins know they are a twin. They don't! They are in their own little world and most babies don't notice their twin is even there for a while. But once they do — look out! You'll be snapping photos left and right of all the cute twinnie moments!
  • You may notice it's getting easier to bottle feed them at the same time. Doing tandem bottle feedings will really cut down your feeding times, so if you gave up on this before give it another try now that they are both a bit more stable.

Personal Advice from Parents of Twins Week 11 and 12

“Be patient. Soak in all the new things they are starting to do. When they start engaging with you, engage back. This is when it’s starting to finally get more fun! Don’t put too much weight in what Susie Q says her perfect twins are doing so well right now. You don’t know how preemie they were if at all, and who knows if they’re actually doing those things… some people just like to seem impressive. And if they really are doing those things, great! They’re not your precious babes. Don’t compare. Maybe try to be a little more diligent about being on a schedule for feeds and naps to help with the sleeping at night.” Sarah C.

“Keep trying to keep to a flexible schedule, if one swaddle doesn't work well try another type, take the time to find good childcare you feel confident in because it makes going back to work much more tolerable, watch their head shape and if it is a concern go ahead and talk to your pediatrician now, download the twiniversity podcast because it offers great advice but also helps to put things in perspective for our lives which is just different than the Singleton moms.” Taylor C.

“Maintain a schedule as best you can. Love on those babies. Sleep when you can. Don't forget to eat. Baby wear! Enforce your boundaires with friends and even family.” Tamie E.

“I’m a single mother of twins and this week they’ve been very alert and loving looking around the room and outside. Getting them in the side by side stroller and taking a walk (weather permitting) has been a nice break from me holding them and they love the scenery and fresh air. Accept help and take a break whenever possible. I love them so much but sometimes I just need 5 minutes to breathe.” Emma L.

“Enjoy this phase. They are getting bigger and more fun. Things will only get more interesting as they get older. Hold them when you can but don't beat yourself up when you can't. Aim to get out of the house at least a few times a week, even if you just take them on a walk in a stroller. It will make you feel good and they will love the air and change of pace.” Brooke D.

Daily schedule sample for twins week 11 and 12

A schedule with twins week 11 and 12 is key! Schedules keep you organized. Let's just say that the importance of organization when you are outnumbered by twins simply cannot be overstated now that the twins are becoming more alert and demanding of your time and attention.

If your doctor has approved for you to switch to an every 4 hour schedule (only 6 feedings per day), here is what that will look like:

  • 12 am feed
  • 4 am feed
  • 8 am feed
  • 12 pm feed
  • 4 pm feed
  • 8 pm feed

At some point (hopefully soon!) you'll be able to stop feeding on a schedule overnight and just feed your babies together when one of them wakes up. This will allow you to get MUCH more sleep and just feel better overall. Ask your doctor when you can start doing this! Even if the answer is no for now, hang in there. It will happen and when it does it will be glorious!

The key to twins is sticking to your schedule, while realizing that things WILL come up to change the schedule. Take it all one feeding at a time. If one twin wakes up to eat, wake the other and feed them together.

Always keep the twins feeding together to make sure you get breaks. If they are on opposite feeding schedules, you will never get a break — and you deserve one!

Sleep advice from The Sleep Lady

Infants are notorious for interrupted sleep. Come to think of it, why do people say they slept like a baby? That sounds dreadful to me!

If you feel like your twins may never get the hang of consistently sleeping through the night and napping, you aren't alone. You might be wondering when things get easier in the sleep department. Perhaps your little bundles of joy lulled you into a false sense of security and slept through 2 whole night in a row and then, BAM! Up all night long the third night. It's all part of the process and those restful(ish) night are coming again!

There are some things you can do to help get some shut eye for you and your twins, and ensure some good sleep patterns for you all to enjoy for years to come.

The Sleep Lady, Kim West, LCSW-C says: “Dutch researchers Vanderijt and Plooij published a book, “The Wonder Weeks,” entirely about these periods of regressions and growth. According to their research, growth spurts occur at weeks 5, 8, 12, 19, 26, 37, 46, and 55. That’s a lot of growth spurts!

Babies may experience sleep regressions starting around 3 to 4 months, again at 8 to 10 months, 12 months, at 18 months, and again at 2 years; the most common sleep regressions occur at 6 weeks, 4 months, and 6 months. It is fairly uncommon for a baby or toddler to have a full-blown sleep regression with every developmental milestone.”

When to call the doctor 

It’s better to overreact 100% of the time than to underreact once.

Use of this site and the information contained herein does not create a doctor-patient relationship. Always seek the direct advice of your own doctor in connection with any questions or issues you may have regarding your own health or the health of others.

When it comes to calling your doctor or seeking medical advice, you have to learn to trust yourself. When in doubt, call. The thing is, a good pediatrician will NEVER make you feel stupid for being concerned about your twins well-being. Remember that and hire and fire accordingly.

That being said, there are a few guidelines to follow.  There are a few circumstances under which you should call your doctor and get medical advice, or even call 911.  When you call you should have a pen and paper handy and be prepared to give the following information over the phone:

  • Immunization records
  • Any medications, dosages, and times last taken (even over the counter drugs)
  • Medical history
  • Your baby’s temperature
  • Mention that the baby is a twin, in case of a contagious illness

Any time you see the following symptoms with your twins you should contact your pediatrician immediately.

  • Blood in vomit 
  • Blood in stool
  • Seizure
  • Suspected poisoning
  • Bleeding you cannot stop
  • Unable to move
  • Limpness
  • A rectal temperature of 100.4 or above
  • Sleeps more than usual or will not wake up
  • Yellow skin or eyes

Call your doctor as soon as possible if one or both of your twins experiences any of the following.

  • Refusal to eat for multiple feedings in a row
  • Diarrhea or vomiting 
  • A cold that will not resolve itself or gets worse
  • Unexplained rash
  • Signs of dehydration (no tears, no wet diapers, sunken eyes, sunken soft spot)
  • Ear drainage
  • Will not stop crying

When to call 911

Please note that when you call 911, you and your baby will be taken to the nearest emergency room. This may or may not be located at your preferred hospital.

  • Your baby is turning blue or taking more than 60 breaths per minute
  • Your baby has a seizure which lasts more than 3 minutes or you cannot reach their doctor by phone immediately
  • Suffers from convulsions, unconsciousness, or irregular breathing following a fall or from bleeding
  • You think your baby may have a skull, neck, back, or pelvic fracture (DON'T move your baby)
  • Your baby suffers from a compound fracture where bone is sticking out from the skin (cover it with a clean cloth and do not touch it)
  • Your baby has bleeding you cannot stop after applying pressure for 10 minutes

Again, learn to trust your gut.  When in doubt, call and see what your doctor thinks.  That’s what they’re there for.

What you should read for twins week 11 and 12

Don't forget to do these things with twins week 11 and 12

You might feel like you're starting to get your bearings with twins week 11 and 12. It's getting a little better each week with regards to sleep and routine, and will continue to. We promise! We have put together a short list of a few things to remember that might help you out a bit.

  • Take pictures and keep a memory book/box! These moments are passing so quickly and you are so busy and tired that you really need to keep a record of these moments to prove to yourself that they really did happen!
  • Keep your own mental and physical health in check! You can't pour from an empty cup! Be sure to eat and drink plenty of water. You're no good to your babies if you aren't well. Make sure you talk to someone about how you are feeling when you are overwhelmed. Your partner, spouse, or a good friend might be a good start, but keep your doctor in mind if you feel you're in over your head. Postpartum hormones are no joke!
  • Keep in close communication with your pediatrician. Keep a running list of questions or concerns so you don't forget to bring it up at the next appointment. Call the office anytime you feel the need to ask more pressing questions. If the staff at the office makes you feel guilty about this, it's time to find a new provider.
  • Teamwork makes the dream work! Burn out is real and it happens faster than you might think with twins! When it becomes too much, lean on your partner and tag them in for a bit. Take a breather and go back in as a team.
what to do when you're having two ad

An excerpt from Twiniversity founder Natalie Diaz's book, “What To Do When You're Having TwoBUY THE BOOK

Enjoying some one-on-one time during your twin's first few months will also help you realize that your twins can thrive while being separated form each other.  Infants are individuals first and twins second, something that is important for all of you to honor throughout their lives. Start putting this perspective into practice early on by bonding with them as individuals.

Here are some easy and fun things that you can do with your one-on-one twin time.  To make the most of these moments and create priceless memories, no texting or talking on the phone is allowed during these activities! 

  • Cherish bath time when you bathe each of the babies separately – you can't beat this precious bonding time.
  • Take one baby out with you for a walk in the single stroller or baby carrier.
  • Take each of the twins separately for doctor's appointments.
  • Bring them to a play group or new mom's group on opposite days.
  • Play with one baby alone at the park or push one baby in the baby swings at the playground.
