I'm not expecting anything. When my roommate's daughter comes into my room while I'm on the computer, she tries to interact with me a for a little while but loses interest after she finds there is nothing for her to do. When I'm in the garden, I can usually find little things for her to do to help me out, like evening out the soil in a raised bed or putting flower bulbs in a bag. She happily does them and it holds her interest. Part of the difference is that the computer doesn't lend itself to collaboration the way the outdoors does. Part of it is that what I'm doing on the computer is far more obscure than what I'm doing in the garden.

If you can provide contrary anecdotes, why don't you?

Edit: Maybe a child can't hunt right away, but gathering can certainly be done by a child. For example, this morning my roommate's daughter was up in a tree picking mulberries.
