After Disney Channel, Nickelodeon, and Cartoon Network, a good next step for your child's TV viewing is ...not MTV. Not for my kids anyway. Tired of The Little Einsteins and sick to the stomach of Barney, they set their peepers on Discovery Channel.
This inquisitive stage really has no age range to it. As long as your child has reached the age of discovery, then it's time for Discovery. So if you have no idea how Pluto lost its planet status, a huge possibility is that Discovery Channel does.
These are just a few of Discovery Channel's plethora of educational offerings that have nothing to do with text book learning. This is extreme education with a generous dash of entertainment and engagement. If you think it's still too much for your kids, think of it as nothing more than a hyped Jimmy Neutron cum Dexter's Lab cum Phineas and Ferb.
Or, think of it as a smart way of getting the WHYS out of your hair for a few hours. There you go! Boom-de-yada... boom-de-yada...
