My LO is almost 6 months old, and just cut his first few teeth.
A couple of months ago, we introduced him to pumped breastmilk bottles, and after some convincing he took to them. Perhaps too well. He started getting very fussy at feedings: latching on, sucking for a couple of minutes, then pulling off, sticking his hands in his mouth, and (sometimes) screeching. He would still take a bottle no problem, and down 5 or more oz of milk, so it seems he was still hungry. We thought this might be nipple confusion, and so stopped giving him bottles, and he got a bit better about taking the breast, but never really went back to his former non-fussy ways.
Now that he's really getting into the teething, he's been getting fussier, and we're worried he's not getting enough milk (he is a long "lean" baby, he looks alright but doesn't have much baby chub to spare). My supply has also significantly decreased in the past two months, as he hasn't been as persistent. He does feed well at night, but we've been trying to feed him less at night, as he's demonstrated the ability to sleep through the night on several occasions and our Ped suggested we wean him off of night feedings.
We decided to give him pumped breastmilk again today, to see if he was still hungry after feedings, and to boost my supply a bit.
He's been fussier than ever, and won't latch for more than a few seconds. I've tried giving him something cold to suck/chew on before feeding (chew toys and frozen wet washcloths), but he just sucks them for a few seconds before fussing again.
Is this just teething pain? Preference for a bottle? Both? I don't want to be pumping all the time, and I'd rather not increase his night feedings, but I don't know what else to do to make sure he gets enough milk.
He still has plenty of wet diapers.
