feed him 5oz. babies know when they're hungry. you're the momma, you call the shots.

my son not even a month yet drinks 5 and is still kinda hungry after that.

He can't get sick , he may just gain weight faster but if he's hungry than he's hungry ! Is he a bit chubby? Some kids just eat more

He was taking 4oz and just recently started taking 5oz his doctor said it was too much and my MIL also says the same thing she tells me not to give him 5oz but i tell her he wants it and she tells me no make him wait! I mean I'm not gonna starve my baby if he wants it I give it to him but I was worried that he could get sick from his tummy or something @adevlin2

All babies are different. At 1 month mine took 3 oz but he was skinny and doesn't like to eat still (almost 2) .. Maybe yours just have a bigger appetite
