Anywa,s this is a pacifer that always closes when it drops out of the babies mouth. I think it's such a great idea, I have one that I bring with my everywhere. (I might not use it all the time, but I do bring it all the time.) This is such a good idea, because pacifers don't stay in the mouth unless it's it's attached to something, and now you don't have to go to a bathroom and wash it all the time, or use a wipe or blow it off.
This one is better, is has animals. I have the red/yellow bumblebee one, I love it and it's probably the greatest pacifer ever. I don't think I ever go back to regular pacifers.
They sell these at CVS. I'm not sure about Walmart or Walgreens or Kmart, but I'm sure they do, and at Babies R US, (if you go there.)
