My kids don't but I do! I watch any and all gymnastics...esp. kids close to my son's age and level to see what's out there. I just watched the men's national competition and WOW- I can see some future Olympians out there.
We started one and love doing it. We took a break when I lost a baby late in the second trimester but we are back at it now. It's Ava Does Life on YouTube. It's not all gymnastics by any means but there is a lot. We love whitneys world, flipping Kate and bratayley too.
I have a couple of channels I really like - beside my daughters of course
piibunina - typically has chinese national gymnast and I love to watch their bars and beam
sporteverywhere - I love that they break down the routines into Code of Points
USA Gymnastics - always great stuff on here
