What’s going on with those twinnies?
Your twins each weigh about 12.7 oz, which is about the size of an endive.
Your baby’s movements have gone from flutters to full-on kicks and jabs against the walls of your womb. You may start to notice patterns as you become more familiar with her activity.
–Decide if you’ll circumcise (if you’re having boys.) This is a decision you should be discussing with your doctor if you aren’t sure.
–Create a phone and email list to alert your closest friends/family after the babies have arrived. Designate a point person in your family to be the one to inform everyone who needs to know so that you don’t have to worry about it. Another idea is to type up an email and leave the babies’ stats blank, save it in your “drafts”, fill in the blanks after the birth, and send. Utilize social media to inform the masses, but make sure that the people who are closer to you find out via personal phone/text/email before seeing it on social media.
–Talk to your parents/closest family/friends about how they can help in the early weeks after the babies are born. Don’t be afraid to ask for help, even if you don’t know how much or how often you’ll need it. Just be forward and honest that you will need help and that you need specific people to be on call once the babies are born and you know what you’re looking at. Here’s a great chore chart to post in your home to help people help YOU when they visit.

5 tips for a better 21st week
–Wear comfortable clothes. You’re not trying to impress anyone!
–Eat protein every two hours, such as hardboiled eggs, cheese sticks, Ensure, protein bar, Greek yogurt, etc. to help keep sugars regulated so your heartbeat can slow down.
–Tell people what you need – they often really want to help.
–Stay positive. Avoid the message boards if they are bringing you down.
–Give yourself a break. Do not be too hard on yourself if you can’t exercise as much as you’d like or you aren’t looking the way you’d hoped. You’re growing/carrying two babies, and that in itself is AMAZING.
Advice from other twin moms
Take it as easy as you can, accept all available help. – Aileen S., Edinburgh, Scotland
Enjoy the journey, seeing your body change is amazing. Embrace it! – Annie R., Moreno Valley, CA
It is okay to feel self-conscious the first time you wear maternity clothes! I am finally at the point where my regular clothes just don’t feel good, and when I try to wear them, I end up tugging and pulling at the clothes and fidgeting to try to make myself more comfortable. At the same time, accepting that my body is REALLY changing at this point feels so strange. I was so anxious about wearing maternity clothes for the first time, but I was SO much more comfortable. – Leslie B., Chicago, IL
Try not to listen to singleton moms and their pregnancy stories. It sounds isolating or rude, but our pregnancies are not the same.
Rest whenever you can! Get as much sleep at night, and nap in the afternoon if you can! Meal prep to help make nightly dinners easier for you, but keep eating healthy. Invest in a pregnancy pillow if you haven’t already. It makes sleeping a bit more comfortable. If you work a job where you’re on your feet a lot, invest in compression stockings. – Emily S., Concord, NH
Get involved with twin moms groups. Try not to compare your pregnancy to others, especially “singleton” moms; it sounds isolating or rude, but our pregnancies are not the same. Make sure you have at least one person you can go to for help or advice. Margo L., Lutz, FL

Concerns other twin moms had
Getting the nursery set up
One baby (mo/di) weighing more than the other
My mental health, I’m hormonally wrecked
My birth plan
The results of the anatomy scan
Planning my maternity leave
I now weigh more than I have ever weighed in my entire life. Coming to terms with that is tough, and knowing that I am only half way there is a little scary.
I haven’t started to be able to feel the babies moving yet. The ultrasound tech explained that it was due to where my placenta is growing, and that it is totally normal. Even knowing that, I am still a bit of a nervous wreck about it.
Whether they will be born super early and whether we will be ready for that
I’m feeling good. No major concerns.
Delivery. I had a beautiful, unmedicated vaginal delivery with my singleton and am hoping and praying for a vaginal delivery with our twins. At our ultrasound last week they were both head down– praying they stay that way!
Gender! Ours are identical, but we’re choosing to not know the gender until birth. I can’t help but wonder though!
Questions twin moms had for their doctor
How are they developing? Equally? (My twins are identical and share a placenta).
Are they the appropriate weight/size?
Am I gaining enough weight?
When will I feel the babies kick?
How much longer will the babies be able to change position before running out of room?
Is it ok for one baby to weigh more than the other at this point?
What are my anatomy scan results?
Is it normal to feel swollen legs?
Cause of itchy belly?
What exercises are best?
What can we expect going forward at appointments?
Any symptoms I should be looking out for?
There was a 3 oz difference between the babies at the anatomy scan last week. Is that enough to be concerned about?
Should I be worried that I still can’t feel the babies moving?
I don’t have stretch marks at this point. Does that mean that I might not get them at all?
I am hungry ALL OF THE TIME. Is that normal?
How early should I go on maternity leave?
When should I stop traveling?
How soon will we have ideas about vaginal birth or c-section?
When will I need to take a glucose test?
Is there anything I can do to prevent going on bed rest?
Will you vaginally deliver a breech Baby B?
Typical tests that are done
Between weeks 18-22 you’ll have a level 2 anatomy scan. This is when you can typically find out the sex(es) of your babies. Don’t be surprised, however, if it’s too difficult to see one or both babies’ genitalia to determine the sex, most often because of the position the babies are in. During this scan, your medical team will be assessing the development of each baby’s brain, face, heart, spine, and other major organs, as well as the placement of the placenta(s), umbilical cords, and amniotic fluid levels. Do not be surprised if you are asked to come back for a follow-up scan. This is very common with multiple birth pregnancies because it’s often difficult for the technician to get a good picture if your babies are not cooperating.

An excerpt from “What To Do When You’re Having Two“
It is important to make sure that are taking your prenatal daily vitamins. If you are tired of paying for your daily vitamins, when you go to the doctor’s office, just tell them to give you a boatload of samples. They will give them to you. I don’t want you to be shy about anything like that ever again. Every time you go to the doctor’s office, just take whatever you want. If you need gloves, ask the nurse for a few pairs! You’re paying enough to that doctor. I mean, really, the birth of your twins will cost almost a hundred grand between your hospital stay, the babies’ hospital stays, plus every freaking specialist in the universe who is going to come witness your birth and probably bill for it. I think you deserve some free vitamins.
I mentioned this before, but it’s worth bringing up again. You need to drink at least a gallon of water a day not only to prevent hemorrhoids and all that fun stuff, but also to ward off dehydration and pre-term labor. If your body gets too dehydrated, your muscles can tighten and cramp, and this can be confused with labor pains, so it is crucial that you remain properly hydrated throughout your twin pregnancy.
