Along those lines, remember that adorable doll house I found for super cheap on Craig's List for Kendall's birthday? Guess how many times she has played with it since she got it two weeks ago? Two. Yep, two. I've noticed that her choice for pretend play is more with scenarios, rather than having a doll in each hand.
For instance...she LOVES it when I get down the bag of random party items (leftover napkins, cups, streamer, etc.). She'll spread them across the room and talk to imaginary people about her party she is having.
