Many days when Louise, Gus and I are home together, I allow them to have time with the art supplies at the kitchen counter while I'm in a nearby room, cleaning the kitchen, or running up and down the stairs doing laundry. Most days, they get along well and create pretty fantastic things. Recently I was folding laundry in my room and came down to find them in the kitchen looking like this.
Fortunately, they were washable markers. Unfortunately, even washable markers require some elbow grease to remove them off of delicate body parts. You should have seen the smiles at the grocery store. Adoration or stifled snickering, I haven't a clue. I smiled proudly.
