My baby is 3 weeks old. we had trouble breastfeeding amd have only started doing it without nipole shield successfully since friday. the health visitor said she should be emptying my boobs. yet tonight she fed from my left boob for an hour and there was still milk coming. she fell off but was still rooting so i put her on the other side. she emptied my right boob in approx 20 mins earlier today. is this happening because my milk supply hasnt adjusted to her needs yet and should i keep her on the on the one side if milk still coming until she is full??? first time mum and finding this all a bit confusing
