I want to teach my kids to sign. :) These are THE best videos for teaching sign language to children. And to be honest, I even learned signs I didn't know :) The videos are well done, brightly colored (but not obnoxious), and all have a theme.
http://www.PattyShuklaKidsMusic.com Beginner sign language. Including words: Yes, No, Mommy, Daddy, Share, Eat, Thirsty, Stop, Thank you, Hurry, Please, Wait, All done and more. And she does it in such a cute way :) This is just 1 of several! I'm learning this for Joycelyn!
