Know how to handle a brat? 
Mummify them from neck to ankles, seal them in a thick leather sack, layer it in straps, then secure your smartass package to the table itself. Weave her ankles through a firm bracket, bind ALL of her toes back, wrap wide tape around their face, sealing the entire bottom half off.
If they still act up, add a Brat Strap. That is, a leather strap placed at the balls of their feet then wound around the bracket, and cinch it off tight.
Then tickle the brat out of their minds without mercy.
