Can anyone tell me if babies can be allergic to breastmilk or just something mom has ate? I've been giving a few bottles of formula a day to see if that helps. He has puked (not just spit up but actual puke where it comes out his mouth and nose) since he was born. Gonna call my dr tomorrow. He doesn't seem to be losing weight. He eats really fast so we have to pace him but he still pukes. ANY advice is appreciated since Thursday and Friday nights he was up every 30 mins. Before that he was up every few hours. Last night he slept four hours then up for a little but then out for another 4 hours. I have been giving him gas drops and one dose of gripe water yesterday.
