I also offer the mom the option of feeding one side and pumping the other. I encourage them to start between 3-8 wks depending on when they are returning to work. The other option I tell them about, and I think more of them do this, is to pump about 1 hour after a feeding. Hartmann's research showed that the majority (can't remember percentage) of milk that is removed during a feeding is replaced in about one hour. In this way, baby is still perhaps an hour away from the next feeding. If less, they will just feed more to make up the difference. I also encourage them to do this in the morning as that is when milk supply/reserves are the greatest of the day. I think if mom nursed one side/pumped one side for every single feeding, it might impact her supply in some way. Might. However, if they only do this once or even twice a day, I think any impact would be negligible.
