Baby is two weeks old. Totally different experience than my first! When she breastfeeds, she nurses for a good ten minutes or so and falls asleep but then just wants to hang on, not drinking just sort of with nipple in mouth and nibbling occasionally? Is this non nutritive sucking and part of cluster feeding and getting my supply up, or flutter sucking? I usually let her do it for a bit but eventually want my boob back. She is two weeks old. What do other people do?
