Do Avent Bottles Attach to Medela Pumps and Vice Versa?
My friend is giving me her Pump in Style Medela breast pump. Does anyone know if I am restricted to only attaching Medela bottles to the pump? I received Avent bottles at my shower and was wondering if I need to return the Avent bottles for Medela bottles. I'm pretty unfamiliar with how all of these bottles and the pump work. Thanks!
