4 Critical Mistakes Expectant Twin Parents Make

If Your Twins Were Born This Week

Your twins are considered to term. They are typically born as healthy as their singleton counterparts. Twins born during the 38th week average a hospital stay of about 5 days and normally go home with Mom when she leaves the hospital.

Tracy M. recounts that her “sweet girls arrived healthy at 38 weeks on the scheduled c-section! I thank God for keeping me calm & keeping my babies in my belly full term, though having lots of contractions starting at 32 weeks!”

Patrick B. had twins born at 38 weeks. His son was 7lbs 8oz and his daughter 6lbs 5oz. No NICU time.

What to Prepare This Week

Frankly, when Mom is 38 weeks pregnant with twins, the time to prepare is past. Wrap up any remaining items you need to handle today. By this time, you should be able to schedule a c-section if needed or desired. Talk to your doctor about the medical reasons for letting the pregnancy go beyond 38 weeks.

Dad’s Thoughts

By the time Mom reaches 38 weeks pregnant with twins, you have hopefully put everything you need into place for the twins’ arrival. If you’ve been diligent over the last several months, you might have a few days rest before the twins arrive.
