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 ldquo;Play with the Limbsrdquo; 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 itmdash;a real educational exercise. By means, of it the child may gain some consciousness of companionship, and thus, by contrast, a deeper self-consciousness.
