If you figure it out let me know too!!! haha
I have 2 boys, one will not jump off the furniture, just off the bed, he's about 4.5 - 5lbs (depending on the day) and the other one has NO fear!! He will jump off anything! He is a bit bigger at about 8lbs and he just feels more solid & sturdy, but he still scares the crap out of me sometimes! Im afraid of broken bones! I tried repeatedly to get him to at least jump off the couch cushions instead of the back of the couch, so at least he only jumps one foot instead of like 3 feet, but nope! and I have hardwood and tile floors!
