I also use glass bottles if I have to use a bottle. I just do not personally like heating up plastic.
And they do not hold the old milk smell.
And with binkys I only use the green hospital ones because other pacy nips can get water inside them and the milk. And it can be a bacteria holder.
The worst for this is mam brand.
i do it every two weeks.... they get stinkyyy ickky....
I want to know too! Bump!
I breast feed most of the time so I do not need them right of but 10 minutes in boiling water does the trick. Just stir them around and air dry so no lint or anything gets on them :)
I did this about once a month bottles and binkys can get yucky and smelly. :)
