Wow, it was great! I think it's not so great for bigger kids (or parents when it's very busy), but she's almost to the perfect age for it. We played with clay, she played in the water tubs, she dug in the rubber "dirt" in the dig pit, and she got to hang around a lot of other little ones. We also had a fun time in the treehouse.
Here she is in the baby area, painting some water in a trickling water feature.
