I have these devices given my 8 months old baby at Easter. It's totally begeißtert of the stones. But even from the beginning .... When I got the package from Amazon and the modules unpacked, I thought to myself ... "The bucket is pretty small." But now I have to say, the bucket and the building blocks are perfect for little baby hands. She was able to directly withdraw yellow lid, which is of course equal wandered into his mouth. The lid can be because of the holes engage prima, turn, turn and feel and you can take him on tiles super make a noise ;-)), yet it remains completely. The modules are color great and have no sharp edges. All blocks were licked at some length and touches. In addition, my baby is auszukippen able with one hand the bucket with the building blocks and to rejoice about how herauspurzeln the stones. The stones can also be stacked super superposed from mom or dad, and then the daughter umschmeisst the tower directly. The devices based on the shapes to get stuck in the lid, you can use 9 months, of course not, but I have discovered another small employment that makes them happy. I put the lid on the floor and sort the blocks into the holes. Thus it is necessary to cover naturally hold, otherwise slipping the modules. My baby has now been developed so much finger dexterity that it can remove the blocks from the corresponding holes. If she has all 5 managed, there is of course a big praise! For me also a big selling point, the plastic stones can be washed without any problems and, if necessary, also disinfected. You are for us, therefore, to take the perfect toy.
