As a mother. Sister you cannot enable/ allow your son to continue certain behaviors because now we see you are part of the problem. Allowing him to jump off, climbing tables chairs is a fall risk and whenever in the future when you decided take him to school. It will be worst because schools or restaurants don’t allow it, its not safe and its a liability issue if that exist in your country, and I’m sure your neighbors or friends think the same. You have to think about that.
