If you want to avoid all those cries of "Moooo-om, I'm booo-oored" you'll want to bookmark this great site from Crayola! It has a whole slew of activities for kids, including:

• Create & Color Coloring Page Maker where you can craft your own colouring book scene to print out and colour.
• Crayola Digi-Color with virtual crayons, pens, pencils and stamps.
• Coloring Pages & Sheets for Kids with more than 1000 pages to pick from.

Although the site is from Crayola -- which is a company in the business of selling crayons -- we thought that the advertising was kept to a minimum and the activities were pretty fun. Your kid can definitely kill an hour or more exploring -- which just might save your sanity!
