My 13 week old was a great feeder till about two weeks ago. He started to fuss while being feed. Now he pulls off after feeding for about 4 minutes. He tries to relatch, sucks a few times and pulls off. He will do this for a bit untill he starts to cry. Then I burp him and try the other side. He usually will feed for less time, maybe 1.5 mintues and then start to pull off again. He seemed to be so cranky during the day. Today I gave him a bottle after a feeding and he drank 4 additional ounces and then was much happier during the day. I have tried other positions. Could the mini pill still affect nursing despit what it says? Any other thoughts as to what it could be??
