I am hoping to get some feedback on the length of feedings that are happening with my 4 week old son. He seems to be thriving (1 mo. appointment is tomorrow) and is happy, but here's my questions: He has started to nurse for shorter and shorter periods of time in the last several days. He pulls away from the breast in less than five minutes, lately. I do nurse him frequently, so perhaps he is just "topping off" but I know it's important to get to the hindmilk for more calories. Is he getting any hindmilk after a five minute feeding? Why is he pulling away so soon, lately? I've seen a similar post mention oversupply so I will read up on that, but I would greatly appreciate any information! Thanks!
