Here’s what to expect when you are 29 weeks pregnant with twins:

If Your Twins Were Born This Week

Your twins are early preterm and the odds of survival are better than weeks past. However, twins born during the 29th week still risk major medical complications. They could spends weeks, if not months, in the NICU. Twins born this week average a hospital stay of about 60 days.

What to Prepare This Week

When Mom is 29 weeks pregnant with twins, set aside some time to talk to your parents. Your twins’ grandparents can help with your twins. They just aren’t sure how or what you want. Talk frankly with them about what you need and what they can do when the twins are born.

Dad’s Thoughts

By the time Mom reaches 29 weeks pregnant with twins, you’re concerned about how to juggle the time demands of twins and other children. Balancing a suddenly larger family is difficult but you can do it. If you think through the logistics before the twins arrive, you’ll be better off when they arrive.

Still wondering how to prepare for your twins? I cover specific things you should know and prepare for in my Dad’s Guide to Twins book. Learn more about the book here.
