Medela nipple "converters"?

Rhianna1981

I am due in July, but I am just trying to plan ahead!

I plan on breastfeeding practically full-time. That being said, I have a Medela pump and plan to build up a small stash for emergencies, babysitters, etc. My Medela pump came with some bottles and nipples, and I am not sure if I should just plan on using those, or buying some other nipples... The only problem that I see is that some nipples that I would like to try (like the breastflow) don't seem to fit on the Medela bottles. Do I just need to buy entire new sets of bottles, or is there some way to make other nipples fit on the Medela bottles?

I am thinking that it would be really nice and easy to pump into a Medela bottle, and use that same bottle to feed, but obviously I can always just dump the milk into a new bottle if necessary... It just seems like an additional step that might be nice to avoid, if possible.
