My 4 year old won't stop climbing onto and then jumping off of things

The couch, the counter, the tv stand, the computer desks, the recliners, the bar, inside the refrigerator, shopping carts, counters at stores, the dogs, his cousins...the little monkey scales something in the second you're not looking at him and then makes eye contact with you on his way down.His mother and I are terrified we're not going to notice him one day and he'll hurt himself.What can we do to stop this? via /r/Parenting http://ift.tt/2q9GRNS
