little girl born at 34 weeks

Eliza
So my little girl was born at 34 weeks and stayed about 10 days in the nicu. We just got her home yesterday and it's a challenge I've slept maybe about 30 min she doesn't really want to sleep or eat much and hasn't had a stool since sat. All this things I'll bring to her doctor attention. 
I'm scared Bc sometimes she turns super red when she is moving and I have to pat her back or call her name why is this ? Also I put her to burp but she won't I'm not sure if I'm doing it wrong
