Query: back to work mom

I recently went back to work, and was unsure if I was going to be able to still breast feed my son. I bought the Isis breast pump and haven't had a problem keeping up with his needs. I liked it so much I went out and bought a second pump just to help the process go faster. The only problem I have had with the pump is I cracked one of the funnels, and you can't find them in the stores, you have to order new parts online and wait for them to be shipped. Other than that it is a great system.
