Climbing

I know that all my children, at some point or another, have climbed and gotten into things and whatever, but I am REALLY confused with this one. How in the world does she climb up on this sink? She usually finds a way. It looks like, in the picture, she dangerously climbs onto that little shopping cart and gets up on the sink. Hmmmmm.....I guess I need to pay a little more attention to this climbing monkey.
