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!

The avent bottles don't attach because they're too wide. The pump does come with little bottles you can pump into then pour into the avent bottles. What I didn't realize when I had my daughter is that not all babies like all bottles. My baby wouldn't take the Dr. Brown's bottles (which do fit Medela), but she did take the avent once we tried those.

I don't know about new models, but the one I had about 2 years ago only allowed for Medela bottles.

I pumped straight into the freezer bags and it was EASY! I used a binder clip (you know, the ones you buy at office supply stores) to give extra security to the bag while I was pumping, but then just squeezed out the extra air and zipped close. Then when I got home all I had to do was lay the bag flat in the freezer and I was good to go. I think I used the bottles that came with the pump twice, and that was the first couple of times I pumped, just getting used to everything. I bought the Lamasil bags, just because I liked those at the time. I think any of them with the zip close top would be good. I just zipped the top closed around the part of the pump that would normally screw to the bottle and put the binder clip above it for extra security. We used the Avent bottles that you just put the freezer bag into. That way all I had to do was send the freezer bags and the bottle and his babysitter just had to heat it and go. No transferring or anything. Good luck!

You can get an adapter. Google "medela" and you should find it at several online retailers. is one that may have the adapter.
However, I simply used the bottles that came with the pump. I even bought extra ones. I liked having 8 or so. For freezing, I would transfer the milk into Gerber Breastmilk storage bags for freezing (one or two ounces at a time for the early months, then 3-6 ounces later). After defrosting I would just pour the milk into the Avent bottle. The bags don't take up as much space in the freezer as the Avent via containers, and it's not practical to freeze in the little medela bottles because you need to use them for pumping.

Just fyi ..I know the Dr. Brown's bottles fit. You would need the narrow bottle, not the wide mouth. This is so much easier than switching over. Sorry...not sure about Avent brand



answers from Dallas on

It has been 4 years since i used the pump but from what i remember, the Avent bottles did not fit especially if they are the wide mouth ones. However, any "regular" bottle will fit on the medela pump, like the gerber ones, those are the ones i used to pump and store then just put the milk in whatever bottle i wanted.
