Prime-Line U 11126 Door Reinforcement Lock – Add Extra, High Security to your Home and Prevent Unauthorized Entry – 3 In. Stop, Aluminum Construction, Bronze (Single Pack)

I’m so sorry. I once found my daughter on a roof. We put these locks on the windows and sliding doors after that: https://a.co/d/028eenQ1 And these locks on traditional doors to outside. Put them very high, at the top of the doors. https://a.co/d/0e4mtlaP

Try putting these up high, out of her reach. Unfortunately the babysitter will have to close it after you leave, but it will stop elopement. https://a.co/d/047KNYnS
