Hello VelvetVamp, welcome to the forums!
I wanted to let you know that the rumor you saw is not real. There are black haired peeps in the game, as well as many other hair colors, but there are no peeps with black lips and everyone's eyes are blue, green or brown. All children can sometimes be naughty and tear books, jump on the bed, etc but nothing like you mentioned. I hope this puts your mind at ease and that you enjoy your little family!
