My Ideas spontaneous fingerpainter- Pillow Thought

I went to put zoey down for her morning nap and come out to this..

but at what point do you get mad at her for finger painting??
she was doing it in the kitchen and not making too big of a mess..
so despite the fact that she did not ask for permission
(which I have to tell her all the time we will paint "later" more times than I can count daily)
I can't help but just soak up her little creative love for paint!
