I may not be remembering correctly, but I think my first real exposure to computers was in the fourth grade. I wasn't interested in them at all. I was so not a fan that I would often try to weasel out of our assigned computer time at school. And we didn't have a home computer for quite some time, so my first time searching the internet and using email was when I started college.
So it is kind of bizarre (exciting, scary, fun) to me that children are now learning to use computers at such a young age. I've seen plenty of little ones manipulating the mouse well before entering kindergarten. And everyone knows how the kids love their iphones. I'm not sure how much we should be focusing on computer time at home. I definitely want to expose him, but there are certainly a ton of other things he should be doing with his time (like massaging my feet and fetching my slippers).

Nate loves the computer and is a big fan of the games that involve the keyboard, like Elmo's keyboard-o-rama (hit a letter and it pops up on the screen with an accompanying word). And apparently he's also very fond of checking his email:
