I don't remember what it is called but I got it at Walmart. It's a little ring with a mesh-like piece on the end. You put fruit in it and let your little one gum on it.

What is that?

It's great, she loves it. It also helps her gums feel better while she's teething.

I have one of those for when my little girl is big enough to start on solids. Does it work well? I'm curious
