This pacifier was for my stepson's birthday. He was very excited when he received it, but then we noticed that the mouth didn't open like it should. So we had to send it back for a new one which took another week. We finally got a new one and encountered the same problem. Instead of sending it back I used a nail file to remove the excess plastic that was preventing my mouth from opening freely. I'm a little disappointed that we had to put so much effort into this mannequin. Now the dummy works fine and he likes it.
