When Erin was born, I was nursing her one day and she unlatched, looked over my shoulder, and grinned the biggest grin you've ever seen. She was only a few days, maybe a week, old, so smiling isn't something she was really readily doing yet.
But I knew that was a real smile, and I had the distinct impression that the smile was for Cora, who had dropped in for a visit. It happened a couple times more too. Patrick did it too, but not nearly as often.
Allison has been doing it a lot. It really warms my heart. I want my kids to have a connection to their big sister. Last night at about 3am I was burping Allison, and she looked up and smiled the most amazing smile. I treasure those little moments.
