Going back to work

Kaity
I start back to work on Monday (and I'm already missing my baby), and I'm worried about my milk supply. I left the baby with daddy the other day and he blew through what I had frozen (15 ozs in 4 hours?!) but my son has been power eating lately. If I start pumping every two hours, will it increase my supply? Will I need to continue to pump that often at work?
