DD is 6 weeks. I have been feeding from both sides in each feed up until recently - wait for her to come off and then switch over. But I've noticed in the past week that she is not interested in the other side when I switch. The length of time she feeds for has also reduced so I guess she's getting more efficient at it and is getting more on the one side and not still feeling hungry when she comes off. When I saw a bfc last week she also remarked that she thought my milk flowed very fast so I don't know if that also contributes. Is it a problem just feeding from one side per feed or is my supply well established enough to deal with it by now? Thanks.
