DD is 3 1/2 weeks old and, now that we've finally figured out BFing, I would like to start pumping so I have a supply in the freezer. I'm going to be working from home so I don't need a lot, but I want to occasionally be able to give her a bottle if DH and I go out or when we travel (we're flying in 2 weeks), etc. What's the best way for me to start pumping? I don't mind pumping at a regular time each day just so I have a supply built up. I have a manual pump (Medela Harmony) but I don't know when to pump, which side, etc. without messing up my supply.
Any advice you have would be appreciated!
