My 4 month old has never had problems taking his bottle before, he was drinking 6oz every 3 hours but suddenly he’s drinking 4oz no problem but then fidgeting so much he’s hard to feed for the last 2oz… He’s been doing it for a few days now and I don’t know what to do? He seems perfectly well and happy in himself? He chews his hands constantly and has been doing for weeks now, he’s constantly dribbling for the past few weeks also. He recognises his bottle and wants it when he sees it so definitely seems hungry but just won’t finish his bottle, it’s like he gets bored!
