My 9 week old weighed 7lb at birth and only weighs 7 15 now. HV says to supplement with formula. My prob is that baby is very very windy (always blue around the mouth) also very sleepy when feeding and will go hours without feed if I let her. She generally feeds every 3 hours and am trying to give her both breasts because HV says my milk may be low, sometimes she will only take 10 mins before falling asleep, have tried all sorts to keep her awake - How can I keep her awake to feed? have tried everything for wind nothing works (all medicines, cranio osteo etc)Any tips? How do I know if she has got to the hind milk? I cant face putting her on formula What do I do?
