I thought I read that the avent bottles were compatible with the medela breast bump? I purchased a pack of 3 4oz bottles today and they don't fit my pump n style. Do I need to wait until she goes up in oz's or for different medela pumps?
I'm using Medela and Avent bottles.
Re: Avent bottles
I'm not sure this is THE one you want, but they sell converters:
