My DD12 "displays" hers but hasn't touched them in about a year or more.
My DD10 will occasionally play with hers - change outfits, etc. - but in spurts and have gone 3-4 months without touching hers sometimes.
Their time for playing with dolls and AG dolls in particular seem over.
However, DD10 still LOVES to play with "toys" like LPS. She builds "villages" with books, cups, board games, nick-naks, etc on our large coffee table and her LPS roams around in the mess. When I tell her to clean up, she complains that she spent HOURS "setting up" and didn't get a chance to play in her village "creation" with her LPS figurines yet.
DD12 has moved onto electronic gadgets like MP3 players and nooks and her new cell phone.
