We ordered the balls together with a paddling pool here .... For our 8 1/2 month old daughter the quietschbunten balls were roaming around in the paddling pool great fun! Highly recommended, low use (costs), high benefit / fun ;-) The ultra-light balls move in the water with every movement of the child with and are alone thus very interesting for the little ones ... Also chasing is make the balls floating in the water on the floor of the paddling pool to the shadow fun for the mice And of course you can see the many funny colorful balls prima rauswerdfen from wading and fishing in again ....
