Did a quick google and it seems most people say it's ok, and do use them again but to just replace the teats. So maybe I was a bit OTT but LO 1's bottles were well loved and I used the Dr Browns bottles which have many plastic compartements...so I'm still glad I replaced them.
Am interested in that too! I have bought new ones anyway for the coming LO as most of the old ones I had were not BPA free. But I do have some that I am thinking of reusing!
Nope. Bottles don't cost the earth and there is so much uncertainty re plastic bottles anyway, that I didn't think it was worth it. Even though I use the BPA free ones, you still never know.
