I thought this would be a great idea for my teething son.  I put some frozen fruit in the little mesh bag and gave it to him, but when he put it in his mouth, it was in there for about 5 seconds and he spit it out and hasn't touched it since. I think the feeling of the mesh was a little disgusting for him.  I'm sure other people had better luck and the product itself seems like a great idea and it's well made.
