My baby started unlatching from my boobs every 2 seconds and crying in this high pitched tone. I put the boob back in his mouth and he unmatched again after a few seconds and starts crying. I don't know what going on?! He was very good st breastfeeding before and this kind of thing only happened a couple times. This is the second time in a row it's happening and I just can't feed him! What's going on?! Usually this means he needs to burp but burping him isn't helping. I'm going crazy!
