Sorting-eye sizes

After Tara realised some of her pet rocks were in need of repairs we got out our stash of googly eyes and were looking at the different sizes.
It was Tara that surprised me with her knowledge of "medium" so we went on to sort "small "medium" and "large" eyes into little cups. It goes to show that our children really are listening to every word we speak. Though i have never explained to her what medium was she had heard it and worked it out herself.
