Hey guys i was wondering if anyone knew if there was something i could take for low milk supply? i always thought i had a good milk supply. bubz always had trouble when she was born with my fast flow and now she is 11 weeks old and im having probs with my supply. she isnt gaining much weight and my partners thinks its time for formula but im just not ready to give it up if theres a way of fixing it. any help would be great. thanx
