DS is 19 weeks and currently has four 8oz bottles a day. I also sometimes give him an extra 4oz bottle mid afternoon if he wants one. He weighs 17lbs 6oz and put on 10oz last week. He seems to want a bottle earlier and earlier. Should I give him more bottles or not? I've just given him a 5oz bottle and then will give him another around 11.30 before his long mid day nap because he was crying for food when normally I'd just give him his 8oz one before his nap. Is this OK? I don't want to be giving him too much extra food or should I just give him as much formula as he wants?
