After our son got home from school this afternoon I watched him playing properly with baby girl for what I think was the first time.
Our son had a squeaker and was moving it toward baby girl while squeaking it. Baby girl looked at the toy, and then at her brother and belly laughed at him.
This went on for a couple of minutes.
I sat back and watched them. Brother and sister enjoying each other's company, and loving each other.
I love those moments.
