Webkinz Jr. (http://www.webkinzjr.com/)

Once you set the difficulty settings for your child's ability level on his or her WEBKINZ JR. account, this site is so easy to navigate that it takes very little if any parental assistance even for preschoolers. The same basic Webkinz world applies here, but without chat features. Each Webkinz animal -- a dog or monkey, for example -- gets its own little house, park, store, and classroom, and it's up to your child to take care of it. No doubt, this site promotes computer use at a very young age. But there are many educationally appropriate games for the pre-K and K set on this site. And the confidence they build by being able to navigate a safe, adorable, intuitive site on their own makes this site among the top picks for the youngest computer users.
