Yoga. . . with kids

It's too hot and too late to go running now in our little heat wave, so I am doing a yoga DVD. It's hard though, to relax and to concentrate on breathing when you hear one baby crying in the background and one child singing a nonsensical, made-up song at the top of his lungs while "Old MacDonald" plays in the background and trash trucks rumble in the background. Still, something is better than nothing. . . right?
