We use the mom cosy one, we rinse it out then use a Milton sterilising wipe to clean it since it can't go in the steriliser
@Rachel thanks, I will get the wipes. I just find the design odd, one sterilises everything and then they have a surface that is difficult to clean.
@Helena thanks. Just had a look and they indeed have much better design than the momcosy one. A woman must have been involved at Inoby!
I use the Inoby portable bottle warmer which has an adapter for Mam bottles and can be sterilized. Really happy with it so far!
