This is the best teether ever!!! My 5 month old is soo picky when it comes to teethers. I tried everything from teething beads, frozen pacifier, washclothes and oragel. Nothing helped for more then 2 minutes. Once i gave this to him he immediately put it in his mouth and started chewing on it. It looks like a pacifier so he knows already to put it in his mouth. I got the all blue one because i heard the multicolor one would comes apart. I love this teether soo much i am going to buy more. I just wish it came with more solid colors. Besides that i love it, my son loves it. Its AMAZING!
