Re: when to start pumping?
I would wait until the week before you start pumping (two weeks before, max). Your supply is very sensitive to external influences so early on, and you can drive a nasty oversupply by pumping too early (speaking from experience). When you do start pumping pick one time to pump every day. Pumping at the same time is less likely to create an oversupply. Mornings usually yield the most milk. You likely won't get too much the first few times you pump, and that is normal so don't sweat it. You can in a second pump during the day if you need it.
Keep in mind that you only need enough milk for that first day (1-1.5 ounces for every hour you are gone). You will need to pump milk for the next day while you are at work to keep your supply up. It's nice to have a few extra "just in case" bottles, but you don't need to overdo it with the pump.
