Last Christmas, DH & I bought the townhouse for DD thinking it was big enough to house her Hopscotch Rabbit family (which we included with) and thought that should be sufficient as a starter. After a day of playing, she told us she'd like the manor and collect more CCs. So beware!
Some of the parts are really cute but tiny (especially the accessories), and the label says it's not for children under the age of 3. I'd wait since your DD is still very young.
