My little daredevil loves to jump off the bed; he has stairs to get on the bed that he uses, but rarely uses them to get back down. We have hardwood floors & he runs full tilt & slides into the wall daily while chasing his ball. He scares me to death & he weighs 8 lbs. I got insurance in case he breaks something, but I have read several threads here about yorkies falling on their heads & dying. Very, very heartbreaking. You protect them as much as you can & try to train them to not jump from elevations; you get insurance & pray that they will never be seriously injured. You don't let them be held by children or unsteady elderly folks unless they are sitting down low. Yorkies think they are bigger than they really are. Yes, they are fragile, but they are still dogs. There has to be a happy medium between protectiveness & letting them be dogs, or else you worry yourself sick & can't enjoy all the yorkie fun to be had.
