What do you do when they don't completely empty that breast before they're done? Do you offer the same breast first next time or do you just leave it and switch sides? Or do you pump after feeding until it's empty? I'm curious because LO feeds every 3-4 hours and if I don't switch sides each time, the other breast feels like it's going to explode! But I'm also worried that if he doesn't empty it I'll end up with clogged ducts? Or shouldn't I be worried about this at all?
