K.F.
My son used the computer with me at that age. I started letting him use it by himself when he was able to manuever the mouse (around 3). We started with www.starfall.com. This is an AWESOME educational site (teaches letters and sounds). I made a shortcut to this on my computer and he knew he could use that site by himself. This was the only site he could use at first. Now we have added www.abcya.com - also educational, but a little higher level. I teach 2nd grade, and these are the two main sites my students use. (The computer teacher does not allow the disney and nickelodeon sites because of all the popup and advertising.) At home we are now doing webkinz world too (they have a webkinz junior as well) but this requires buying a stuffed animal to get a code and then the child takes care of the animal online. Hope this helps!!
