"sissy"

I went in to wake up Holden this morning. Zoe came in and got on the bed. She went up to him to give him a kiss and he said "sissy". Her eyes got SO big and she said "mama, he said SISSY". I said "yes, he did sweetie". He smiled. When it was time to take her to school, I told him we were taking sissy to school. We walked into the garage and he said "sissy" again. It just made her day. And mine, too.
