You will laugh.

There was a circle wide enough, the baby penetrated that circle and that's why it got hurt. If people were getting kicked left and right I'd put more blame on the dancer but it was the kid that entered the area. Plus the dancer was facing the opposite direction so there was no way he could've avoided the kid. On the parent's side it is possible the baby squeezed through some legs and that's how it got to the dancer before the parent could stop him.
