Is it safe to use bottles that are 2 years old?

Or should I just get new ones, probably a silly question but know DH will query the need for new so thought I'd ask. Presuming old teats should be binned too. Thank you!

I think teats are supposed to be replaced frequently anyway not sure about the bottle but i would get new.

Yes I had a feeling that was the case, thank you, I shall visit the store tomorrow.
