Can I opt to have the same training as the kids instead?

For a start if you trained in defense only you're already at a disadvantage. Taking the exact same training they took would do the following.

1) You'd know exactly what to expect.
2) You'd be the aggressor rather then the other way around.

These two are significant advantages over the 5 year olds. A few reasons, the most of which is sheer strength. There is no doubt about it, you will be stronger then a 5 year old.

Not to mention even in an organized circular assault from toddlers, there is only so many that can get to you at one point. And that is probably less then 10. The rest of the time they are pushing and shoving to get to you.

These mindless, fearless kids attacking you are still weak in structure, let me explain.

My first few seconds on battle.

Grab the closest kid and snap his arms like twigs. Grab the next kid do the same. By this time the kids are probably all around you. This is when you start picking them up and hurling them at the other kids. I mean really tossing them.
You would easily start just punting them away from you.

If it starts to get too much I'd make my way over to a wall by just up and charging, stomping the kids along the way. Now they can't get to me from all angles.

My number - 40 if it's defensive trained, 80 if it's the same training as the kids took. Knowing what to expect is by far the biggest advantage in any fight.

According to the "Percentiles" what doctors use to chart the averages for all kids.

5 year old male will be 3'7"(50%) tall, and be 41lbs (52%)
