I pumped when my milk came in, b/c I was so engorged my nipples were flat and baby couldn't latch. The pumping relieved the pressure and drew my nipples out. You want a good supply, but you don't want an oversupply and be uncomfortable all the time.
i know a lot of women on here nurse and pump at the same time, baby on breast, pump on the other, and they get good results this way. I don't do that (I never figured out how to do this comfortably, and I never needed to). The first 6 weeks I pumped almost exclusively, only nursing maybe 2x a day. Once I went back to work at 7 weeks PP, I nurse almost exclusively - baby gets about 4 bottles a week (I am only in the office 2 days)
on days you don't have baby with you, pump about as often as the baby would eat, every 2, 3, or 4 hours (whichever falls with the baby's routine). When you do have the baby with you, pump after a feeding, this should be more hindmilk, which is not a bad thing. When you pump and feed expressed milk, baby gets fore and hind milk all mixed together. I could be wrong, but I don't think there is any harm in that. also pumping after a nursing will make sure baby is getting enough in that feeding and any you pump is truly excess.
hope this helps!
