I haven't started pumping yet but need to start because I'm going back to work soon. I am wondering, my son usually feeds from both breasts in a feeding session lately. That makes it confusing for me as to how and when in any given day I should pump? I have read that some people pump the breast their baby isn't on, but I would be robbing him of milk if I do that because he'll move to that breast after he's finished with the other! Any suggestions? I don't want to only give him hindmilk or only foremilk so I really want to do this right.
