Worried 😩😔❗️

My son was born 11wks & 6 days early 😩 he was born 3/17/18 & I’m just so scared because he was born so early. He has mild complications such as undeveloped lungs & feeding issues but overall he’s doing well. He uses a feeding tube & he’s on oxygen until further notice, I’m just so scared guys😔. He’s my first & I would be devastatedif anything happened to him. NEED ADVICE! HAS ANYONE HAD THEIR BABY THIS EARLY? HOW IS YOUR CHILD DOING NOW?
