If you pump while away from your baby:

How old is your baby?
How often do you pump?
How much do you get either per pumping session or the cumulative whole day of pumping?
How much and how often does your baby eat (per bottle)?

I'm trying to figure out how to handle my return to WAH when DD is just over 4 months. I will likely have a babysitter just mornings and I'm not yet sure if I want to have the baby brought to me for feedings or pump.
