Good for winter clothes.She can empty the closet, label the shelves and tubs and sort. Target, Lowe's and Home Depot have the shoe cubbies to store shoes in. They are really worth the money.You can get the over the door shoe bags to hold bottles of things, it is very helpful. Sets of baskets are good for holding things.

So encourage her to do one part at a time. Dresser, Night stands, Bed, Closet, chest. Good Luck.Mom it is your Job to guide her. You are her role model.You are her example.
