My son is 3 weeks old and is or seems to be always hungry. I was finding this very stressful it seemed that he was hungry as soon as I was done breastfeeding. I decided to pump and breastfeed, that way my husband could help. He is eating about 4oz every 3hrs and though I am producing enough I am worried he is eating too much. He does not vomit anything afterwards but it seems like so much more than what other people say they are feeding their child. My mom says that if he is satisfied and not vomiting afterwards it should be okay but I am nervous to tell my pediatrician how much he is eating.
