it's strange because i thought all my avent bottles have a really small "7" on the bottom of them but they don't!!! i must have been seeing things. does everyone have a little circle though on the bottom of their avent bottles?

do you think it's best to wait to see if it's really that dangerous? i am seriously thinking of going out tomorrow and getting new bottles but i don't want to waste money if it turns out to be not that bad???
