DS is 5 days old and formula fed, for the 1St few days he was fine but now he will down up to 3 or 4 ounces, bring it back up then start screaming, especially when we have to lay him down to change his clothes as he's covered in sick. As soon as we pick him up into an upright position he seems to calm down and settle. He seems to be most comfortable either upright or sitting in his rocking chair. The midwife said its wind but we've used infacol, burped him regularly throughout feeds and even if he does burp he still ends up basically projectile vomiting then screaming again. He seems to be wanting to feed alot too which I've heard can be due to the swallowing of liquid easing the sensation of the acid coming up. I'm wondering if to change he's formula but don't know to which one? Every time he feeds, coats us in vomit then starts screaming I just want to cry
