I practice yoga with two toddlers running around and banging toys and crawling on/over/under me! Sure it is annoying, I wish they'd leave me alone a little bit, but I also think the exposure is so great for them. Both of them are fairly good little yogis from doing toddler yoga on YouTube (Cosmic Kids Yoga) and from watching/participating with me when I do yoga. I sometimes do it in the evenings when they are sleeping, but I've also learned to just go with it when they are awake. I work nights so I am usually with the kids from when they wake up until they go to the babysitter after lunch and I go to work until midnight, so it's either I do things with them awake or things just don't get done! Sometimes I get disrupted or my posture has to get altered due to a squirming body beneath me, but I just do the best I can.
