Right now Babygirl breastfeeds every 2-3 hours. She'll do about 20-30min on 1 side and then I'll burp her and she'll do maybe 10-15 min on the other side and I'll burp her again. Does this sound Right? Or should I be doing something different. Also when should I introduce pumping? And how do I go about that.. like do I do it every time on both sides and just put it in a storage bag? Can somebody tell me how to work it into my specific schedule. Or tips please
