How to breastfeed both breasts?

I am trying to breastfeed using both breasts but when I am feeding on one breast the other one is leaking like crazy! Does anyone have a suggestion to keep this from happening? I'm holding up my pump to the other breast to try to catch the milk coming out. I don't know if I should just feed on one breast and then pump the other and feed it to my LO with a bottle?!?
