If Your Twins Were Born This Week
Your twins are very early preterm and the odds of survival are better than weeks past. However, twins born during the 27th week still risk major medical complications and life-long health issues.
John W.’s twin boys were born at 27 weeks and weighed 1lb 13oz and 2lbs 3oz. They spent 79 days in the NICU.

Your Fellow Parents at 27 Weeks Pregnant with Twins
Jamey M. – “It’s getting rough. The additional weight is really starting to take a toll on my body, especially my knees and low back. Its frustrating getting tired just doing laundry or making dinner.”
Tom B. – “We now have four bassinets ready; two for both up and downstairs. Lots of clothes ready to go. My wife is starting to really slow down and finding it hard to sit up from being seated or in bed. The excitement is definitely building for me, but I think the tiredness is wearing on her!”
Omar A. – “Mom feels fatigued much of the time and tosses from side to side at night.”
Melanie C. – “My wife is feeling uncomfortable and chronically in pain. She’s exhausted and hungry and emotional. It’s a scary time for me if I don’t feed her regularly!”
By the time Mom reaches 27 weeks pregnant with twins, you should be well on your way to preparing any other children for their arrival. This includes making your own plans for how you’ll juggle the twins and a toddler (or other children).
