LO is nine weeks old (10 on saturday) and has been taking 3 or 4 oz of breastmilk in a bottle every 3 hours while at daycare. Today, I came home and gave him 4 oz for his 6p feeding, and he was acting soooo hungry, so I breastfed him until he unlatched and seemed full, which was another 15 minutes or so. I'm wondering if I should move up from 4 oz bottles to the big bottles and give him more for daycare. I'm afraid of overfeeding him. Is that possible?
