Baby: spit-up, diarrhea, excessive sleeping, fussiness, and small temperature?

I breastfed mine the first two/three wks and it wasn't cutting it for him. I tried how many formulas before switching to soy and that switch didn't actually upset his stomach at all. If you aren't burping him good enough, you can pat harder or rub their back in circles to help get it out. It won't hurt them doing it a little harder. They aren't as fragile as they seem. Mine takes forever to get them out. You should burp every two ounces, but its easier to get them out if you do less
