I am constantly amazed at how their little brains work! My 4-year-old grandson came to my daughter and told her that when he is big and has unsightly body hair, she will have to buy him a Nono hair removal system. Because, "it's better than shaving and or waxing." He then proceeded to repeat almost the entire infomercial. He is very concerned about that unsightly body hair. Oh! And she has to buy him the brown one because the pink one is for girls, and maybe even the blue one, but the brown one is for boys. He's dead serious.
