How old is Luigi? Tiah was a lot worse with jumping when she was youger (under 2 years). She seemed to think being in mid-air was the best place to be
! Landing was just an added bonus for her. She (sometimes still) would jump from THE TOP OF THE BACK OF THE COUCH TO THE FLOOR!! And not just at the foot of the couch, out across the floor as far as she could! Oh, it is infuriating because you can't stop them in mid air. That must have been terribly scarey when he landed on his back and didn't move....your heart probably stopped
. I am glad he is doing fine now. I wish I had advice for you. I know I could say don't let him on the furniture, but I know the reality of that not happening. Good luck. If he is still pretty young, you have the calming down to look forward to
