My son was born @27 weeks exactly, he was 1 pound 7 ounces he was born with a open chamber in his heart that didn't close called PDA, he had surgery and he's been doing great every since, this Sunday he will be 1 month old, he has another hole in his heart called VSD if it gets bigger as he grows he will need a open heart surgery before he comes home.. But if it shrinks or stays the same as he grows he should be fine cuhz its not big but not small.. so I pray it gets smaller, here is a pic of my baby boy today 1 pound 10ounces.💪😍😘👣💙 Friday was the first time I got to hold him cuhz he got off one breathing machine and skipped the next one now he's on a mask he's doing great, the first time I held him I cried it was a long 3 weeks and one day that I waited and yes he's our rainbow baby and our first baby
