My baby girl is 2 and a half weeks old, breastfeeding is going really well, and I've been given the go ahead to start pumping. I'm not going back to work until December (she'll be 4 months old) but my mom lives close by and really wants to be a part of her life and start watching her. And I would appreciate the break too!

I ordered a hands free pumping bra (the simple wishes one) and I have a Medela PISA. Yesterday I pumped twice, but I am super nervous about timing the pumping. I haven't had engorgement or leaking yet and it seems like my supply is just right for my baby.

I want to start building my stash of frozen milk but I'm not sure when to pump! And I don't want to create problems with oversupply. Any advice on when to pump?
