I am looking for some advice about my 15 year old step daughter. Nothing too serious like drugs, alcohol, or sex, but she isn't able to keep her room clean. Her room was smelling like a zoo. She is sneaking food, for example, a found a bowl of powdered sugar in her room, ewww. I also am having problems getting her to understand that she needs to take care of the items used during her period, found several used items under her dresser......
