This site offers many activities for young children. Actually, it is designed for children and their parents. There are shape coloring pages, number coloring pages, and alphabet coloring pages featuring the familiar Sesame Street characters, all of which may be downloaded for your child to use. You will find an interactive book to read and games to play. There is a comprehensive list of topics and parenting information which most parents should find useful. This site is definitely building toward the future with many innovative features, so if you're running Windows 3.1 or Macintosh you won't be able to play their games. Be sure to read the guide for their recommendations.
Many toddlers used to enjoy the Elmo graphic that would jump when "tickled", but that was removed recently. It is a site that does change to keep things interesting. So check it often with your children and remember--Learning is Fun!
