Most parents prevent children from drawing lines like this. And children dislike coloring. While I see you yourself helping to draw it with your daughter. Even if she fills her hands and feet with colors, you are not disliking her but happily supporting her. And this is a positive thinking. I am a mother myself and I also love children's play with colors. But I've seen some parents who don't like their kids putting colors on their clothes or getting it on their hands. And consider this thing as dirt.
I like your way of thinking very much.
