What would you do?

When your almost 2 year old is coloring his mouth with a green marker during our fathers day craft (my best guess is he thought it was chap stick? lol) do you?

A. Grab the camera because you this this will make a cute picture then immediatly take the marker and scrub his face/mouth
B. Grab the marker out of his hand as quickly as possible and wash his mouth with soap and water
C. let him keep coloring as long as he wants
D. After taking a picture tell him we don't color on ourselves but don't take the marker away or wash it off immediatly
