Won't somebody please think of the children?

[Lord Iames Osari]

I'm a big fan of the normal way of doing things, ie bonus to pysical stats, penalty to mental ones.

As for being outgrappled by a child... well, have you ever tried to grapple a truly unruly child?

The child may usually win, but I think that's due to the fact that most adults don't use their greater strength and mass to full advantage because they don't want to hurt the child. I'm confident that if I really wanted to, I could wrestle a smaller child to the point of serious injury or death.

In D&D terms, most people will voluntarily take a penalty to their grapple check when wrestling with a kid, so as to avoid doing any harm.
