Parents need to know that although kids younger than 4 can probably use this site with some simple pointing and clicking, we don't recommend kids that young going online. Based on the WGBH TV show and seen on Discovery Kids, the site offers fun family activities for both online and offline play.
My two year old loves the interactive games. They make him laugh. He wakes up saying, "Peep." The activity articles are great. Overall a really terrific site.
