Breast Pumps!

What is your favorite breast pump? Have you tried more than one? Why do you think it’s the best?

I will be going back to work after I have my baby and want to continue to breastfeed for at least the first year. I would appreciate any and all advice.

Ameda Purely Yours Ultra Personal double electric

Freemie Deluxe

Hygeia Enjoye
