I bought this for my daughter when she was teething. She enjoyed playing with it as a toy, but didn't seem to get much relief from it for a teether. She liked shaking it to make the keys clank together, and as she grew older she liked to carry her "keys" in her purse, but as a teether, it wasn't her top pick.

I have these Nuby Icybite teether for my baby. My 9 month old baby does not really like them. I find that they are quite big for a babies mouth. Maybe it's because my baby has a small mouth lol. They are quite hard has well my baby prefers softer teethers.

This worked great for my baby who is teething. She calmed down after I gave it to her and it really seemed to make her feel more comfortable. Definitely worth buying!
