EBF andpumping?

Stephanie

I am exclusively breastfeeding, but I'd like to start pumping to develop a freezer stash because at some point I'd like to introduce my son to a bottle. For those who exclusively breastfeed, how do you incorporate pumping for the sole purpose of creating a freezer sash? I worry about not knowing if my son wants to cluster feed, and if I pump and and he ends up wanting to eat right after me pumping, what do I do?
