i was just wondering if anyones health nurse has told you that you baby isnt putting on much weight. My 1st baby was bottle fed so i never had this prob but my 10 week old girl is bf. She was born 4300 (9lbs8) she is 10 weeks old and weighs 4740. There is nothing wrong with my supply. She sleeps and is happy after feeds. Shes been smiling for 6 weeks now so she must be happy. My health nurse thinks she isnt getting enought fatty milk. but i have no idea how im suppose to help her get fatty milk??? anyone had this prob? or got any suggestions? that would b great
