Oh thanks ladies, so basically its not that they run out of milk if that is even physically possible, more that they are doing something wrong to make it go so low?
Soul, I'm not sure that this is fair or true. A friend of mine was breastfeeding with no problems what so ever, then at around 4 months she noticed that her DD was getting very irritable during feeding and becoming very unhappy and unsettled to the point where she was always crying, trying to feed (constantly on the breast) and not settling. After a week or so she felt that her DD was losing weight so went to the MCHN to weigh her and she had lost 400g in a few weeks! My friend was doing everything right and the same as me but for some reason she was having problems with supply and for her daughters health (as obviously 400g is a huge weight loss) ended up suppementing with formula (she would BF then give her formula and her DD always took the full recommeded amount even though she had just BF) and she is so much happier now, she has put on weight and looks a lot better. My friend wasn't doing anything wrong it was unfortunately one of those things, sometimes the body doesn't always function the way that it is intended to.
