My ds is 13 weeks old and he seems to have reduced his bottles to only 4 bottles a day his last feed is at around 10 pm, he usually has around 24-28 oz a day. My worry is that at 3 and a half weeks he was 11 Ib 14, he hasn't been weighed since but reckon he's about 14.5 Ib now. I know roughly they're supposed to have 2 oz for every pound but some days he's fine on 24 oz, should I be worrying or not? he has plenty of wet nappies and poos about once a day so is satisified but is he having enough with 4 bottles ..he won't take anymore! I should also mention that he's started to chew his hands loads and watches us when we eat , does this mean he's self weaning? or is he teething?
