Teaching kids about swordfighting

[Shay]

Our house rules:

Rules: Swords are to hit only other swords
If a sword is swung at a body part, the attacker is out for the day.
Swords are NOT to be swung at shields.
You can block with your shield, but not attack with it.
If you raise your shield over your head, that is the signal for a time out of the end of the bout.

(Oh, I also have helmets for them, no worries there.)

What do you think? Too ambitious? Our oldest is eight, and she loves the swords... I'm just wondering if there's something we could throw in to teach her a little more than fighting fair.

(BTW- I consider this sport, not actual combat training)
