my son has been teething since 12 weeks, as soon as he could grab things I gave him this teether and he loves it! we just lost it this week and I have to order him another one, because nothing soothes his pain as well as this one!!! the colour is not the most attractive thing, but it does the job!as soon as he sees it, he is so happy. you can was, sterilize and cool it in the fridge. perfect for little hands as its not heavy as other teethers! Absolute must have!
