It seems like a lifetime ago that I had a child living in my home. I'm at the opposite pole from you, Stevie .... happy for any time that my children have for me. They are busy with their lives and families/boyfriends. We are the generation that was involved in the minutia of our kids lives. It's tough when that ends or evolves.
However , having said that....nothing, absolutely nothing prepared me for the joy that a little 22 month old could possibly bring to two people. I leave to babysit on Wednesday ! Can you see the smile on my face?
