My son is 6 weeks and I was feeding him about 5-6 oz every 3-4 hours. One of my husband coworkers, who is a grandma, told my husband that our baby is eating too much and shouldn't have a belly as big as he does. So my husband had my cut his feeding down to 4oz every 2 hours, but the baby normally starts cry and trying to suck on his hand about an hour to an hour and a half after he eats and it makes me feel bad because I know he's hungry.

I'm not sure what to do. Do I feed him the 4oz every 2 hours, just keep feeding him the way I have been, or go talk to his doctor and get her opinion?
