(3) Order restitution to the aggrieved party.

(b) The dispositional orders are to be in effect for the time limit set by the children's court, but no order may continue after the minor reaches 18 years of age, unless the dispositional order was made within six months of the minor's eighteenth birthday or after the minor had reached 18 years of age, in which case the disposition may not continue for more than six months.
