Hi ladies Charlie is now on 6oz every 3-4 1/2 hrs and sometimes sleeps up to a max of 6hours through the night. He has a bottle about 7pm but after this feed he is really naggy until his next feed and seems to be hungry so i made him another ounce tonight and he gulped it. Ia 7oz too much for 5 weeks? He was 7lb11 born and im guessing he is over 10lb now hes growing loads and has gone up a clothing and nappy size I wonder if i should change his milk if its not filling him? I asked my doctor and he said to try hungry baby milk but ive read this causes constipation?
