Query: A must have!

I got this because I thought it looked interesting. It has been my son's favorite thing to chew on for 5 months now! I read a review that said the berry part came away from the handle, but I have not seen any evidence of that, and it has been used quite consistently the whole time I have had it. I personally wouldn't put anything in the crib other than a regular pacifier anyway, but I did not notice any signs on wear on it, even after 4 teeth and constant use.
