It is such a sweet sight to see TJ being gentle and kind to his sister. One of my favorite things is when he shows something to Julia, and explains it to her in a higher-pitched voice than his usual tone of speaking.
"See Julia, this is a banana," he'll say, showing her a piece of toy food, holding it right up to her face. "See, Julia, it's a banana."
He'll repeat it, which is something I know he gets from watching us. It's nice to know that he is picking up some good habits.
