Chenoa

I have no idea what to do, my two week old baby keeps spitting up, like a lot. He will do it when he’s sleeping a lot too. He was sleeping and i left the room and when i got back there was a bunch of throw up all over my bed that had to have been projectile. I try to burp him after he eats (he breastfeeds mainly, only bottles sometimes) but rarely burps. He burps every time during bottle feeding. I leave him upright for 20-30 min. I even been having him sleep in his hippy lounger when i’m awake to keep him elevated which he seems to like a lot. I change his diaper, then feed him and half the time he poops during the time so i have to change him again and he has a little spit up during that time. And then after that he wants more food. He overeats a lot, for his bottle he would eat 5oz at least every 2 hours if i let him. I’m going insane.
