My DD is 5.5 weeks old and I'm bf. In the evenings she wants to be on my boobs loads and I'm sure a lot of it is just her comforting herself. It means my dh doesn't get involved in comforting her. Should I get a dummy or could it still cause nipple confusion at this stage? Alternatively, my mil suggested giving a bottle of cooled boiled water to give the baby something to suck - but surely this could fill dd up and mean she feeds less, which would affect my supply? Should I just let her use my boob?
