My little guy was born at 32 weeks

He has an intestinal infection. He's been off food for 8 days now. Going to get an x-ray in the morning. He started choking on his throw up. They don't know why he's throwing up. He doesn't have anything to throw up. But he seems content and his belly is soft. So they don't want to do more xrays than need be. I'm worried about the infection he was doing good than Bam this. They said it's looking like it's not the bad infection. I guess that's a plus. I'm worried scared and I cry all the time. I need to get tougher for him.
