Thanks ladies @dominicmommy29 @skyy12221 yea I don't think they will choke on them if they were such a choking hazard I'm sure they would have horrible reviews, which is not the case, from what I've read @mrs.mccormick
I got one for my son, he didn't start getting any teeth until after he turned one he's only had it since February. Not sure if it works cause he's not a hard teether and his teeth don't bother him. He still wears it but even if it doesn't work its still a cute necklace.
