We bought this toy for our 7 months old, boy. When we then had in hand, we did not believe that he really does something could begin. But the toy surprised us. The design of our little stones can hold it very well. This is also the first toy, where we can actively play nicely, as we build various towers, which he can fall down to like again. In addition, he always gives them into the bucket and rattles around like crazy with it. He can sorting it certainly is not, but that is then a further fun for later. In short: He loves it - and we therefore also.
