my baby hasn't eaten for almost 5 hours and he has been up for an hour now. I have tried to feed him a few times because he gets fussy, and he acts like he wants to eat, but as soon as he latches half on, he screams bloody murder. He did this last night both times he woke up. The first time, my DH actually heard him because he was screaming for 15-20 minutes. He acts like he is in pain. I gave him tylenol at that time. My DH said maybe he was hungry. I told him that I had already tried to feed DS twice and he wouldn't eat, but lo and behold he ate just fine. When he woke up 4 hours later and started to cry when I fed him, I gave him Tylenol again. This morning, though, DH said no. He doesn't want for baby to get to the point where Tylenol doesn't work. And baby did calm down after just 5 minutes (which he WOULD NOT do when he woke up the first time - 15-20 minutes of painful screaming - broke my heart). He screams every time I try to feed him, but is fine (although fussy periodically) for the most part. He will suck on a binky, which he is doing right now. He also won't let me put him down, so I have him in the pack and he is currently falling asleep. I thought he was teething and maybe that was the problem, but maybe not.
Oh, also for the past few days, DS has hated his favorite side. He will only eat from that side in the football hold. He has done this several times on the other side, so even though he hasn't ever done this with the other side I wasn't worried. But maybe all these things go together.
Now he is asleep, without eating. He hasn't ever done this, he likes to eat. He doesn't feel like he has a fever or anything. Any advice or ideas of what could be wrong?
