When Brooke was little, she was into everything. Now she doesnt tinker as much - she is more of a thinker than a doer. I'm not sure her brother will follow that same path. He's a natural tinkerer, and he is getting into all the same trouble she did ... earlier. He also is doing things that she would have never dreamed of ;)
As for his current trick? He found the light switch.
Brooke did the same thing, but Ryan did it about 2 months earlier than her!
