In this era of Cartoon Network, Pogo, Disney channels it is impossible to allow children watch TV.
My son, now 5 yrs old, while watching TV keeps the TV remote in his custody. I also work and I am back to be with my Kid early evening. From 2 pm to 5pm he is with grandmother. As in every house she is interested to watch some serials during the day time.
One day, the my mother-in-law could not find the remote control any where in the house and could not watch her favorite serial. The son came back from school, kept his school bag, of out of it removed the remote to swich on the Television and watched his channels !
I think excess of everything is bad and anything should not become a habit. Else POGO is a great channel to watch.
