maybe a dumb question - can these go into the sterilizer?

yes

and not a dumb question :)

Even dimmer question... what is that?

lol @trezelle they're breast pump parts. and thank you @coraanne !

yes

lol haha ohhhhh gotcha

I wouldn't put them membrane in there. other wise you'll probably have to replace them. if you do I think you can just take them apart

I put mine in there

u always put mine in the there too... Better sanatized and to have to replace them every so often then to get baby sick.

sorry I meant "I" always put them in there

lol
