So my LO (16 weeks) has always been a voracious eater and eats every 2 1/2 hours (give or take a few minutes) pretty much like clockwork all day. He sleeps from about 9-6 at night.

Yesterday, he started crying and I put him on my breast and he freaked out (it was time to eat anyway). Wouldn't take it and got louder. I tried maybe 5 times over the next half hour and he just wouldn't take it. He ended up finally taking it about an hour later. Next feeding he took it but was fussy. Next one he freaked out again. Wouldn't take it, finally did after many tries. This morning he ate fine at 530ish. Then again at 8. I just tried to feed him again and as soon as he got into the position to eat, he freaked again. DH soothed him and he was happy. I tried to get him to latch again. Nope. He is napping now. Sigh.

Dunno what to do and what is causing this. I wonder if he is teething because I can see white under his gums and he is a drooler/chewer like crazy lately.

Thoughts?
