It’s all hard work.

What’s Going On With Those Twinnies?

to do list

To-Do List

  • Announce your twin pregnancy to the world (or wait until you’re comfortable). Traditionally folks wait till the second trimester to tell the universe, and you may want to join them. Some folks are very clever coming up with pregnancy announcements, while others simply just blurt it out in casual conversation. It’s up to you to decide how, when, and with whom you share the news, but we are glad you are sharing it with us 🙂 
  • Ask your social network for referrals to other parents with twins you can talk to or meet in your area. Time to start digging in and find a local twins club and even start researching local pediatricians. Your local moms group (twin specific or not) is a great place to start with referrals.

twin pregnancy advice

Advice From Other Twin Moms

  • Try to rest as much as you can. Don’t overdo it. Even at work, you have to slow down some. You are carrying two sweet babies. Your body is already working hard before you even go to work. – Michelle G., Columbia, TN
  • Be excited to finally be out of the first trimester. Enjoy sharing the news with family & friends! – Anonymous
  • Keep eating as healthy as you can. And don’t forget to drink water. I’ve also been drinking Ensures to try to keep some nutrients in me. – Shandi J., Aurora, CO
  • Get as much sleep as you need! Eat what you’re craving. Listen to your body. – Liz B., Philadelphia, PA
  • Drink lots of water and several snacks a day! I am so much less nauseous this pregnancy because I have been vigilant with eating and drinking. – Joanna R., Franklin, TN

twin pregnancy concerns

Concerns Other Twin Moms Had

  • Twin-to-twin Transfusion Syndrome (listen to the podcast above)
  • Just health, and hoping that they don’t come too early.
  • Big “life” things – needing a bigger house, bigger car, how we’re going to afford it all.
  • Worry that I’m not eating right.
  • Worry that I’m going to get huge.
  • Can I really afford to go back to work and pay for daycare for twins?
  • Everything. I feel like the whole process is scary because my twins are high risk. I’m not sure if that ever goes away.
doctor questions

Questions Twin Moms Had for Their Doctor

  • What testing should I expect?
  • Do I need to have any special considerations for exercise?  
  • Can I do prenatal yoga?  
  • Do I have any lifting restrictions?
  • Can I have normal sex?
  • What can I use to ease constipation?
  • Do you ever try to deliver vaginally or always c-section?
  • At how many weeks do you induce?  
  • What type of twins do I have? Di/di, mono/di, or mono/mono?

Typical Tests That Are Done

Chorionic villus sampling (or CVS) is an optional test and is typically offered between weeks 10-13 of pregnancy, when the test results might have a significant impact on the management of the pregnancy. Chorionic villus sampling can reveal whether a baby has a chromosomal condition, such as Down syndrome, or other genetic conditions, such as cystic fibrosis. Ultimately, the decision to have chorionic villus sampling is up to you. Your health care provider or genetic counselor can help you weigh all the factors in the decision.

Typically, first trimester screening is done between weeks 11 and 14 of pregnancy. First trimester screening is a prenatal test that offers early information about a baby’s risk of certain chromosomal conditions — Down syndrome (trisomy 21) and extra sequences of chromosome 18 (trisomy 18). First trimester screening includes a blood draw and an ultrasound exam.

what to do when you're having two

An excerpt from “What To Do When You’re Having Two

Twin mamas suffer from many of the same problems as singletons, ranging from simple discomforts to life-threatening emergencies.  We are just so lucky that the discomforts start earlier and are often more severe. Count yourself doubly blessed for these all too common pregnancy complaints.


The number one complaint of all twin mamas is fatigue.  If you’re someone who used to burn the midnight oil and now you’re passing out on the couch at 9, just throw in the towel, man.  Don’t feel bad about it. I always laugh when I hear women who are carrying twins ask, “Why am I so tired?” You’re building not one, but two humans in there.  That’s why. Go to bed already. Go to bed now. You have my full permission…
