Parenting

So my three year old has, since she was little, been really into jumping. I try to warn her that she could seriously injure herself, but this hasn't happened yet so she doesn't think I'm serious. But she jumps over and off anything. Sisters bunk bed to the armchair 2 meters away? No problem. Bunk bed to the floor? Sticks the landing every time. I swear my partner must have cheated on me with a f##king spider monkey.

How do I convince her to not do the jumps that could break her ankle if she lands wrong? I'm not getting through to her. I'm happy she is physically active, but she's taking the piss.
