Hi - A "Yoga for Kids" program taught by Jodi Komitor may be found here: https://grokker.com/yoga/kids-yoga/program/yoga-for-kids/5b2aa3ed59a78e3cd220e9d1. Enjoy! :)
If your young one is a baby rather than an older "kid", you might like a video made by Ellen Barrett with her own baby years ago: "Happy Baby, Fit Mama". Ellen Barrett has a dozen very popular walk/dance videos here on Grokker; you could check them out here on this site to gauge whether you enjoy them. The "Happy Baby, Fit Mama" video is available on DVD at amazon.com, and it's also available on her $6-per-month online subscription site, ellenbarrett.com, which features about four dozen workout videos that are guided by a very similar philosophy to Grokker's: yoga, pilates, dance, wellness.
