I bought this wristband teether because i have not seen any like this in local market yet, and I always have fear of my baby dropping her teether and putting it back into her mouth again (I am a paranoid mother, yes i know), so with this wristband teether, it encourages baby to hold the teether at the same time preventing it from dropping on the floor, my baby loves it a lot. It is so soft and flexible, so don't worry about it hurting the baby at all!
And it is also adjustable so you can adjust to your baby's comfort and not too tight on the wrist. I guess this is also good for hand eye coordination! Definitely will recommend this to my friends who are also expecting or have little kids who are teething!
