What Happens When the Grandparents Teach the Kids New Tricks?

I have always tried to slow Brayden's climbing down. When he was a baby and would try to climb up onto the couch I would life him up. This worked for quite a while and kept him out of some trouble. He has always been a cautious one, watching Sydney do it first and when she succeeds without hurting herself he'll go and give it a shot. Well what happens when the Grandparents come over and start teaching your kids new tricks??? They become addicted to climbing trees! Not only tree's but now they've discovered a whole new world out there, climbing the fence, trying to get higher and higher.... so fun for them, not so much fun for the paranoid mother!
