As a parent, I agree with most of what has been posted above. I really try to limit the amount of TV my children watch, but I do think it can be positive. Aside from what has already been mentioned, I do like to use the morals of the story in my childrens lives. If one of my daughters is acting ungreatful or spoiled, as ask her why she is acting like a step-sister (from Cinderella) instead of a princess. It seems to help from time to time.
Pre-schoolers can become dependent on television for their entertainment, taking away opportunities for imaginative and creative play. Pre-schoolers who watch too much television can fail to learn how to successfully socialize with others. Pre-schoolers who watch limited, selected television can learn a balance between being entertained and entertaining one's self. Pre-schoolers who watch too much television can lose their incentive to be active and engaged with the world around them. Pre-schoolers who watch no television will undoubtedly be just fine--except one day in the pop culture categories on Jeopardy!
Hah. I have a preschooler. I'll give you a couple observations:
- If used in moderation TV can be a great reward/motivation.
- If used in moderation TV can be a great educational tool (ie: vocabulary development, letter/number recognition, etc.)
- If used in excess TV can cause laziness, lack of creativity, lack of attention, inactivity, no desire to run around, eventual obesity, inability to self-entertain, lack of patience, lack of appreciation for hard work, etc.
"Mike TV" from Willy Wonka and the Chocolate Factory is not an entirely untrue picture of what too much TV can eventually lead to.
