Very Young Children and Boxing

I watched the Contender last night. I am not a boxing fan, however, it came on after the Apprentice and a local was on it so I started to watch it. Surprisingly the show was not as bad as I thought until the fight. Both boxers in the match had young children. The children were at the boxing match! Some of these kids were pre-school age. One little girl had a look of horror on her face when her daddy was getting hit pretty hard. I cannot believe that anyone would allow such a young child view a boxing match much less one where his or her daddy is fighting. Or am I wrong?
