Should kids learn how to be independent at an early age or wait so that they will have something to look forward to?

Independence should come in stages. It should start young and build through the years. Also, just because they learn to be independent doesn't mean you can't still do for them.

For example: My eight year old knows how to make her own Sandwiches and mix her own juice. I don't always make her do it, but she feels good about knowing how to do something to take care of herself.

There will always be more to learn and look forward to.
