Thanks for your replies everyone

I put it around her ankle tonight, but you're right it is a PITA cause she waves her foot around everywhere while I'm trying to do it up! I don't think it will fit around there for long anyway, but just didn't know if it was a choking risk having it around her neck (not from a swallowing POV but if it got a bit tight around her neck because she moves around quite a lot in her sleep). I took it off for her day sleeps today, but might just leave it on. it's a bit annoying taking it off/putting it back on all the time and I'm worried I'll forget about it!

Myboys- interesting about the MCHN! Will have to see what mine says next time we visit. I figure whatever helps/works is surely a good thing!
