To round off some of the activities we did today, here is Otis playing with some keys. I remember my sister (much younger sister) playing with keys when she was little. When Caspar was young and wanted to play with my keys I didn't want to risk losing them. I had this set made up, the keys are all blanks. I keep them in my bag, when I reach for mine or find myself waiting, I give Otis his set to play with too.
I'm sure it's not just my kids but all kids that love keys.
