Twins Born at 35 Weeks: What to Prepare For

Your babies are considered born preterm if you give birth before 37 weeks of pregnancy is completed (37+0 weeks). Twins born at 35 weeks are considered moderate to late preterm, which means that you’ve hit a major milestone.

They’re no longer considered born very preterm. This is according to the World Health Organization (WHO), who subcategories preterm birth based on gestational age.

extremely preterm (<28 weeks)
very preterm (28 to <32 weeks)
moderate to late preterm (32 to <37 weeks)

What happens to twins born at 35 weeks?

Twins born at 35 weeks may not need any medical treatment. They may be able to go straight to the maternity ward with you. In most cases, they’re now able to breathe by themselves.

The main thing they need to do at this point is to grow and gain weight. They may need help with feeding, but not necessarily. The staff at the hospital should guide you and help you with breastfeeding when the time is right.

If you’re not able to breastfeed right away, it’s important that you start pumping. For the first few days, before your milk comes in, hand expression is often the most effective way to express colostrum.

Colostrum is the first milk your breasts produce during pregnancy.  It’s much thicker than the milk that is produced when your milk comes in. It’s a yellowish or clear fluid and full of antibodies and immunoglobulins.

When your milk supply increases, it changes from colostrum to breast milk.

How big will my twins be?

Your babies measure approximately 46 centimeters (18.11 inches), when you’re 35 weeks pregnant with twins. The median weight for dichorionic twins in this week is 2486 grams (5lbs, 7oz).

For monochorionic twins, it’s 2386 grams (5lbs, 4oz). Have a look at our estimated fetal weight charts to learn more about how dichorionic and monochorionic twins grow in the second half of pregnancy.

Can I do something to help my babies?

Frequent skin-to-skin contact is good for both you and your babies. It comforts your babies and helps them adjust to the “new” world they’ve been born into.

Skin-to-skin contact is – among other things – also associated with a decreased likelihood of infection.
