Anyone who has or expects to have children should read this article about preschool learning as soon as possible.
After emphasising some of the importance and benefits of preschool education, it lists some basic and simple ways in which you can help educate your bairns. As usual with such material, there are 'obvious' things that never occurred to me - like placing a young baby face-down from even one month of age, because he will naturally want to raise his head which will help build up his back muscles which will improve general strength and co-ordination. The paper-crumpling trick is clever too.
Well worth a read!
