I ordered these for my 6 month old daughter. There is a good variety of noise makers and different types for her to gum- all just the right size for her age. It keeps her very interested and working on her handling skills. I felt especially comfortable that all of them came individually wrapped and all fit into a simple, small plastic case. I can rotate them. My older daughter thought it was fun to open a new rattle/toy every couple of days. The whole case fits easily while we travel. What a great developmental purchase. I would highly recommend this product. Thanks!
