We thought we'd seen it all ? when it comes to Phoenix, at least ? until a friend brought us to the Arizona Doll & Toy Museum. This small treasure, tucked into a historic house in downtown's Heritage Square, is a wonderful monument to childhood. Antique dolls from different decades share their home with more modern Betsy Wetsy types. There's even a period school room all set up for the dolls. We won't tell you everything that's there ? we don't want to ruin the surprise ? but make sure you go, and take a kindergartner along. You'll both have fun.
