What to Expect with Twins 18.5 Months Old

  • By the time your toddler reaches 18 months, they may drop their morning nap. Keep in mind, it’s perfectly fine for an 18 month old to still be on a schedule with two naps, as long as it doesn’t interfere with their night time sleep. 
  • By this age, most toddlers tend to know what many household objects are and what they do — a hairbrush is for your hair, a shoe is worn on your foot, and so on.
  • Right now, it might be hard to talk on the phone or with a visitor — your toddlers want to be the center of attention, and they’ll letting you know it loudly and clearly.
  • This is the age when children start to test boundaries. Your twinnies may say “no” to any new situations or start to throw a tantrum to get their own way.
  • Your little ones are sporting an almost-full set of toddler teeth, your brushing routine is more important than ever.
  • At 18 months, your child should also be tested for autism as well as for general development, according to the American Academy of Pediatrics. This would be particularly important if they show signs of developmental delay.
  • Your only halfway to 2, but they seems far older than 1½ years. By now, your twinnies probably have plenty of developmental tricks to show off, like walking, scribbling and climbing.
  • Their sense of humor may also be blossoming — they may laugh when you catch them hiding under the table, or squeal with delight when they recognizes their reflection in the mirror.
  • They probably still have a stubborn streak — which can be just as maddening as it is maddeningly cute!
  • If you haven’t already, look into joining a local moms of multiples club (aka twin club). Read about local twin clubs here or join our Twiniversity monthly twin club on Zoom by signing up for a Twiniversity Membership.

Challenges You Might Experience With Twins 18.5 Months Old

There are some challenges to look out for with twins 18.5 months old

Tips from Parents of Twins 18.5 Months Old

Take some tips from experienced twin parents!

  1. Expect tantrums. They are normal at this age and should become shorter and happen less often as your twins get older. 
  2. Play with your twinnies by rolling balls back and forth, pushing toy cars, and putting blocks or other items in and out of containers.
  3. Use positive words and give more attention to behaviors you want to see. Give less attention to those you don’t want to see.
  4. Encourage “pretend” play. Ex. Give your twinnies a spoon so they can pretend to feed her stuffed animal. Take turns pretending.
  5. Give simple choices. Let your twinnies choose between two things. For example, when dressing, ask them if they want to wear the red or blue shirt.
  6. Take more pictures than you think you should. They will LOVE to look at them with you soon!

Feeding and Nap Schedule for Twins 18 Months Old

You’re really going to want a schedule for your twins! Be adaptable, but try to be as consistent as you can. Here is a suggested feeding and nap schedule for twins 18 months old. You will notice that milk is primarily given in addition to a meal, not used as a meal itself now.

  • 7:00 am — Wake up time!
  • 7:30 am — Breakfast with Milk
  • 8:00 am – Playtime 
  • 9:30 am — Snack Time
  • 11:45 am — Lunch with Milk
  • 12:30 pm — Quiet Time before Nap Time
  • 12:45 pm — Lights out for Afternoon Nap
  • 3:15 pm — Wake up from nap
  • 3:30 pm — Light Snack
  • 3:45 pm — Playtime
  • 5:30 pm — Dinner
  • 6:30 pm — Bath and Bedtime Routine
  • 7:30 pm — Lights Out

Do the best you can every day to keep them on the same feeding and sleeping schedule. When you get off track try again for the next feeding or nap.

Do everything in your power to feed your twins together to make sure you get breaks. If they are on opposite feeding schedules, you will never get a break — and you deserve one!

When to Call the Doctor

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

Natalie Diaz, Twiniversity Founder and Mom of Twins

All content on this website, including medical opinion and any other health-related information, is for informational purposes only and should not be considered to be a specific diagnosis or treatment plan for any individual situation. 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. If you feel something isn’t right, it probably isn’t when it comes to your twins. When in doubt, call. That’s why the offices have an answering service and staff on call at night or on the weekends.

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.  Believe it or not, they’re happy to help.
