Hey it happens. Lol! My son was eating 3-4 oz at 3 weeks old and I was worried that I was giving him too much but I wasn't.

yeah i have a big baby anyway with a big appetite lol @amiliz06

It's so hard to say how much he should eat. I would definitely talk to his pediatrician and see what they say. He could be going through a growth spurt.

see 4 oz isnt enough for my son anymore he will be a month Wednesday but eats a 4-5 oz bottle and then not even an hour later he eats atleast 2-3 more oz so i dont know how much i should be feeding him at one sitting now @amiliz06

Oh and he's been eating 4oz for about a month now.

For my sons 1st month checkup they checked height and weight and he also got his Hep B part 2 vaccine. We also went over any concerns I had as well.
