I would let the other children invade her space. As a matter of fact, both of their personal spaces. The ring leader ( I have one of those) will not like it at all:glare:. She can watch everyone play with her things, but is not allowed to join in. Your little follower will learn that she needs to think about the consequences of following her sister into trouble. Make sure the whole family is involved. Congregate in their room. Pull out the babies and barbies. Color in their special coloring books. Whatever is special to them, poke around in it. Make sure they see you having fun, and are not allowed to join in at all. Then talk to them. How did you like someone in your special stuff? Did you like everyone playing with your things? Well, that is how ??? felt when you went pilfering in her room. Let them know it is not a nice feeling.
Good Luck! My little meddler is now 12. They just get more inventive.:glare:
Not sure if this helps any, but ther you go! :001_smile:
