I need a breast pump for my baby.

Hello! My name is Kayla, I am due September 5, 2014 with a baby boy named Candon. I am in desperate need of a breast pump for him. I don't mean to be picky but I've heard nothing but good things about the medela pump in style breast pump. It says that you can get way more milk with these pumps. So that's the one I'm wanting to get for him. I feel horrible that I can't afford to get him what he needs. I am on medicaid and I called to see if they will give you one (I heard they do) but they said they only give them to high risk babies in my area. Please help if you can, I don't know where else to turn to and my baby boy will be here soon. They are expecting him to come early. Thank you so much.  God bless!!
