My children are all blessed with an artistic eye and they love to express themselves in some of the most creative ways.
While this may not be the most creative way to express themselves it is easier to remove than on the walls or floors (which I have plently of already).
I had to laugh when I caught my 3 year old coloring on my baby. I ask her why she has to draw on her sister. She replies simply, "I'm making her pretty mom!"
Well, what do I know anyway, I just mom!
Then a few days later, my 2 year old comes out of the bedroom sporting this....
I just laugh.
