Our 9 month old inherited jumping from her mother and leaping from her father. She is absolutely most HAPPY to jump up on the foot stool when playing ball and jump off when we throw the ball, or any other of her toys. If we're on the floor playing she will leap from one of us to the other. These are things she has grown to LOVE but we worry about there being some long term problems to her legs and joints from all this. Are we just being overprotective?
