When my children were three and two years old, my cousin and his glamorous fiance came to stay. The fiance wore beautiful makeup at all times, even to bed and the children were fascinated with her. Not knowing much about little kids, she left her makeup bag where it could be accessed by my son and daughter. My son gave them both a pair of heavy eyebrows and lip outline with the black mascara brush. To finish off, he then poked the brush into each of both their ears. Of course it was waterproof and we were unable to remove it as any scrubbing was too abrasive on their baby skin. Can you imagine the stares when I took them to the store!
