To fit a child you need a JSP wheel ratchet harness suspension which has 2 positions for fitting the wheel ratchet element to the suspension strap that goes around the head. It comes fitted to the 2 rear points on the strap but you may move them to the forward points thereby reducing the circumference sizing of the suspension strap. This will fit a child.
The 5260R Screwfix helmet operates this way.
