I ordered one I heard it works we'll be finding out soon...my cousin says she wraps the necklace around her daughters ankle when she goes to bed to prevent a choking hazard.

@kambam thank you!

Got mine on inspiredbyfinn.com

He's worn it since 5m to bed and everything.

What kind did you get? And do you take it off at night?

Get one! The sooner the better. We love ours, super cute and I think its helping.
