I have a 3 week old baby boy who I have been expressing breastmilk for since we left the hospital. I would really like to breastfeed but he screams like he is being tortured everytime I try. I am really concerned about the amount I should be feeding him. My pediatricians office just doesnt give me a straight answer. I have been feeding him about 2.5 oz every 2.5-3 hours. Much of the time he acts like he is still hungry right after he is done or he will wake up after 1.5-2 hours and be rooting around again. The doctor said I should feed him 2 oz every 3 hrs. But that just doesnt seem like enough for him. However I dont want to overfeed him either. can anyone help?
