Ultimate fantasy representation of parental control

Hi all, I'm trying to create a page for kids in fantasy style. I need to have a parental control page only for parents. This will be represented by some symbol. So I want to tap into all your creativity out there. My question is this:

What would be the ultimate fantasy/rpg style of symbol for parental control??

What can be on a fantasy page that would make every 5-8year old kid understand that it symbolises parental control page??

Some thoughts I've had so far:

• A grown druid holding hand with a kid.
• A knight blocking the way with a shield.
• A kid inside a wooden stop sign.

Well, thanks for all inputs.
