Review on 8pcs Baby Teether Toys Set - Early Educational Gifts for 3 to 12 Month Newborns and Infants, Grab Shaker Teethers by Mitch Wright

No need to worry. However, they don't make much noise due to rattles. Some of them have teeth silicone, but most are hard plastic. I bought this for my 6 month old daughter and she is almost 10 months now and still doesn't pay them much attention. They're just no fun, with no lights and almost no noise. You have to blow the trumpet, the child can't do that, you have to press the "flower" hard so that it squeaks, the child can't do that. The moon consists of 3 small pebbles, so there is almost no noise and everything else doesn't matter. Maybe my kid just loves loud toys.
