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 spend weeks, if not months, in the NICU. Twins born this week average a hospital stay of about 60 days.
Here are the experiences of a few of your fellow twin parents:

Tim J.’s twins, born at 29 weeks 4 days, weighed 3 pounds 5 oz and 3 pounds 7 oz and spent almost 7 weeks in the NICU. Their time in the NICU was spent helping with feeding, regulating their temps, gaining weight, and keeping their oxygen levels regulated. They had a few episodes where they would stop breathing and have to be stimulated to keep breathing otherwise they were breathing room air in the first couple of days.
Marie’s twins were born at 29 weeks and one stayed 7 weeks and one 8 weeks in the NICU.
Natascha S.’s twins spent 8 weeks in the NICU after being born at 29+4.

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.

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.
