My daughter has lactose intolerence and now has SMA LF and she is now gaining weight, but I am concerned that I still feed here 5oz every 2hours and that she has a dirtynappy after each feed so 8- 9 times aday and none of the doctors are concerned they are just focusing on her weight gain which is 4-5 oz a week. Please help she was born 7.12oz and at 11weeks she is now 10lb I am going mad with worry !!!!!!!
