"Slope Ropes. These are a favorite of ours. Slope Ropes combines the control of a harness, but with the ease of using them (or not) for partial runs or with multiple kids without having to completely move the harness from kid to kid. It’s a large circle of rope with 2 plastic bars/handles at each side. The parent holds one end and the child skis inside the circle with the other bar across their hips. If used properly, your child balances and controls their own weight and speed, but you have the peace of mind of knowing they can’t just take off down the mountain out of control. Bonus: You can reverse your positions and help pull your cute little dead-weight on the flat stretches."
