How much should my 5 almost 6 week old be eating? I'm a mom of 3 and I know if he's hungry feed him and I know he won't over eat . However some people are saying u should be feeding him 6 oz bottles every 3.5 to 4 hrs and I'm not. I'm only giving him 3 oz ever 3 hours and he seems so content with that. I feel like 6 oz is alot still.
