"By the time he is four or five weeks old it is safe to play with him a little every day and Froebel has made his "Play with the Limbs" one of his first educational exercises. In this play the mother lays the baby undressed upon a pillow and catches the little ankles in her hands. Sometimes she prevents the baby from kicking so that he has to struggle to get his legs free; sometimes she helps him so that he kicks more freely and regularly; sometimes she lets him push hard against her breast. All the time she laughs and sings to him and Froebel has made a little song for this purposes. Since consciousness is roused and deepened by sensations remembered experienced and compared it is evident that this is more than a fanciful play; that it is what Froebel claimed for it a real educational exercise. By means of it the child may gain some consciousness of companionship and thus by contrast a deeper self-consciousness."
