An Old Picture

My husband found a dilapidated tin full of old pictures. This one is Elaine, but I'm not sure who the baby is. I know it's not one of my children, because the only child of mine she ever met was the oldest, and Carina's hair was dark and curly. I'm wondering if this isn't a nephew or niece of mine?

Whoever the child is, I love the look on grandma's face...lots of love for a little Valentine.

Update: The baby is her first grandson, Philip.
