I received one of these as a gift from a coworker. My 4-month old loves it! He's not quite teething yet but he wants to put everything in his mouth. This keeps his mouth and hands busy so I don't have to worry about what he might grab next. He loves all the textures. It's easy for him to hold and when he's done with it, it fits perfectly around my wrist so my hands are free. Great gift! (Posted on 8/6/11)
