Hi everyone my baby was born 10lb 3oz and I weighed him when he turned 11 weeks old and has been gaining hes now 15lb 2oz. He has around 850ml in a day though and this is way under the recommended amount for his age. GP said he should be taking over 1000ml Should I add in another bottle? He'll drink 270ml then on his next feed only want say 210ml. He feeds at 9am 1pm 5pm 9pm.
