The Little Blue Door

I'm sure this is the same dilemma that most parents face at some time or another. They find their precious children doing something they shouldn't, but at the same time it is really cute and funny.
What to do?
Do you stop the child and tell them we don't do this because it is dangerous/messy/etc. or do you grab the camera snap a few shots then remove them from the situation and explain why?

I took the pictures.

Call me a negligent parent, but it was too cute to pass up. I swear I was only 10 feet away standing at the stove making dinner when Malcolm got in the air return duct. I could hear him playing with the foot stool and when I leaned back to look through the doorway I could hear him but not see him. Malcolm had arranged the foot stool so it was directly in front of the 'hole' climbed in and was sitting down when I found him. I took four pictures in under a minute and these are some of the positions he got himself into. I then picked him from his new hiding spot and told him it was not safe and not to do it again.
