That's the thing. You're trying to have a good time, and your kid is trying to have a good time. Small kids are very excitable and they forget boundaries. It's just not quality time if you have to keep telling them over and over again to move back and always keep it in the back of your mind that on any given swing of the arm you have to watch for the little ones that could be creeping over behind you to get a better view. You can't concentrate on the game at all yourself so the benefit is weighed down by the cost.
At that point it's better to get a board game out (which we do all the time now). Or go outside with a football.
Yep.
Both times my 3 year old got whacked, it was her moving from one side of the sofa to the other for a different view of mommy bowling.
It was new to the house, and we were not as cautious as we should have been. Now we don't have any problems. We simply show my daughter what we are going to be doing, explain what will happen to her if she gets into that "Wii Zone", and then of course (actually returning to the real world) either my wife or I hold her while it is the others turn.

Seriously though...
It just takes a heightened sense of awareness. The Wii is an EXTREMELY fun family gaming machine, and I am sure that even my 3 year old feels those early whacks were worth it, because even she has a blast rolling the ball down the isles in our very own bowling alley.
