I am a new mom. My daughter is 4 weeks old. Her first 2 weeks of life she lost almost a full pound. Pediatrician told me to start supplementing after feeds and to drink more to increase my milk supply. Did this for a week, she was taking 2 oz of formula after bf for 1/2 hour. In 1 week her weight went from 7# 2 oz to 7# 14.5 oz. I had also rented a hospital grade pump and started to take fenugreek. was pumping out about an ounce to ounce and a half after feeds. dod had me bf for 15 minutes on 1 said and reweighed her after and her wieght went up 2 oz. so he told me to cut the supplements back to only during the night. We were doing fine with that for a couple of days,however the last 2 days she has been extremely fussy after her feeds, always crying and acting hungry after her feeds and now I am only pumping out about 1/2 ounce after feeds. I haven't changed anything else. My baby is not happy, and I am not sleeping. I don't understand what has gone wrong over the last 2 days. I am getting so frustrated that I am ready to give up all together. Any suggestions on what could be going on? I really don't want to stop but I want her happy and healthy.
