Today we finally checked out Notasium in Durham. It’s a music-based indoor play place and they also have karaoke and music lessons. I was really impressed with it and the kids both loved it. There was a bouncy house and a big slide. Helen Jeanette climbed up and slid down the slide twice before deciding it was too scary and then she climbed up several more times and insisted I climb up and slide with her. 
Oma Leni met us there and the kids had a blast playing with her. Chris came at the very end and had just enough time to go down the slide with Helen Jeanette once.
