My little one is 5 weeks old and I've been breastfeeding since day one. In the beginning I was having trouble with him latching on, so I began using a pump and I fed him the milk from a bottle. He is now drinking 3 oz. In order for me to pump 3 oz I have to pump 3 times within a 3 hour time frame. I've heard the quantity of milk varies from the pump vs. from when he is directly on my breast. Recently, I've been feeding him direclty from the breast and i feel he is not getting enough. He seems frustated and begins to cry after 15 minutes on each breast. In order to satisfy him, I have had to give him formula. Each time I pump, I'm only able to pump 1/2 oz from each breast. Is this normal? Is 3 oz too much or too little? Any suggestions on how to increase my milk supply? I want to get away from feeding him formula.
