My son (almost 2) took the pen he was using to draw with and drew all over his leg while I was cooking dinner. I wiped it off, but he drew really hard. There are scratches where the pen lines were. Not deep enough to draw blood, but hard enough to leave ugly red marks.
That's okay, right? lol. My mom used to tell me we'd get ink poisoning from drawing on our skin, but I figured she was just lying,.
