The Peggy Rathmann Official Web Site provides information about the Caldecott award-winning children's author and her many books. The site is simple, easy to use and navigate, colorful and engaging.

Ideum redesigned the site in anticipation of the release of The Day the Babies Crawled Away. This critically acclaimed book was released in the Fall of 2003 and published by G.P. Putnam's Sons. Ideum worked with Peggy to animate one of the scenes from The Day the Babies Crawled Away using Macromedia Flash.
