This invention relates to a harness for securing a person to a supporting structure. The harness includes a pair of straps each having a first and second end, a back portion, a front portion, and a chest portion. The first end is looped over the front portion of each strap and attached to the front portion to form a first loop. The first loop is attached near each second end of both straps. A coupler is near the second end and spaced from where the coupler is attached to the straps. The coupler is separable and may be separated to allow said straps to be separated at the chest portion. The harness goes over both shoulders of a toddler, behind the back and the coupler fastens across the toddler's chest. This prevents a toddler from standing up when wearing the harness.
