Working moms breastfeeding.

S
I am freaking out about how to continue breastfeeding when work starts. Pumping is still going nowhere. Flow is good and the baby is primarily breastfed (gets a bottle of formula before sleeping at night though). How does everyone do it. It takes half an hour at the least to feed him, every two to three hours. When do you find time to pump? When do the nipples get any rest?
