Just made it to 4 wks with my daughter. The other night, she didn't sleep during the day and cried several times until we could comfort her that night. She seemed hungry and if we let her, probably would've fed or suckled all night. We broke down around midnight and gave her formula and she slept until 6am. I've tried pumping, but can only get a little more than a total of 2 oz from both breasts, but she can now finish about 4 oz of formula in one feeding! What do I do?!
