Hallo! For a couple of weeks now, during the days especially, my nearly four month old daughter has started to take a very long time to finish her bottle. She'll drink about half in doublequick time, and then start mucking about - pushing the bottle out of her mouth, then shoving it back in forcefully (I'm holding the bottle, by the way - I don't make her feed herself!), chomping down on the teat, making impatient little grunty noises, moving her head from side to side. She's clearly still hungry because when I take the bottle away, she gets pissed off, so I don't think it's that I'm force-feeding her or anything.
It's not especially bothersome in itself but I wonder whether she's trying to tell me something: I suspect she might be starting to teeth around now, could this have anything to do with it? Also, does this sort of behaviour at feeds indicate that I should start thinking about weaning her soon?
Any advice appreciated muchly.
