Like many products of this famous brand (!), These cubes of activities are suitable for young children and especially its evolution. From 3 months to 2 or 3 years, the child will discover the different "functions" and the different interests of his toy. If he will only hit the "head" of the cube to 6 months, he will find pleasure in naming illustrations sides (dog, cat, moon ...), playing make them appear and disappear at will behind the flap or sliding system ... My 2 year old son found them at the birth of his little sister (like all his toys first age !!!) and turned them into toy bath. So they have a second life, unexpected.
