I have a lot of trouble trying to figure out when my baby is done nursing. I give him one side, he sucks for about 5 minutes aggressively and then just starts to suck a little, stop for awhile, suck a little again, I let that go on another 5minutes or so. So then I stop, change his diaper, burp. I try putting him back on, sometimes he sucks, sometimes he fusses. If he fusses I stop. However sometimes I offer teh other breast and when i do this he sucks like crazy again. So I think he empties out the first but still wants to eat. So I don't know what to do. I can't figure out when my breast is empty, I can't figure out if he gets hindmilk, I can't figure out if he is satisfied and if I should offer the other side. This whole thing is a mystery to me and I just want to do the right thing. What should I do? Oh he is 7 weeks old, I thought I would know what to do and how to read him by now?
