Awww, Judy!It's scary when your babies grow up, I imagine. My sister, brother and I are all right in a row (currently 22, 21 and 20)--so I can't imagine how my mom handled us all going through things fairly close together. And my sister was held back--so she and my brother were in the same graduating class!
It'll be okay, Miss Judy! Just enjoy them as much as possible at every age!
