Ds3 is 13 weeks he's always been between the 9th- 25th centile for his weight. He sleeps through the night and is generally a happy baby. I make him 6oz bottles of aptamil 1 he has 5 during the day he often only drinks around 4-5oz. Is this enough? Dc1 was born a similar weight and was on hungry baby milk at around 8 weeks ds2 was heavier born and was taking around 8oz at this point. How much does/did your 3mo feed?
