I don't even know how he got the stool over behind the couch. I am guessing he had some help from a certain big sister but she says "I didn't even do it mom".
Kathleen is full of stories about Vaughn climbing all kinds of things. They including a street light pole and the refrigerator, just to name a couple. So I guess this is just a case of "like father like son".
(I am not looking forward to the first run to the emergency room....but I can see it coming.)
