You are my Sunshine!

I am usually telling Ella to stay off her brother or don't get too close, but when I caught her singing him "You are my Sunshine" my heart melted and I didn't mind her being too close. If you listen close enough to the end where the verse is "so please don't take my sunshine away", Ella changed it to "so please don't take my Lukie away". I thought it was very sweet.
