That's just so incredibly cute!!!

And a miracle that it's caught on video.
It reminds me of a special friend I had as a toddler. He had a lot of temper tantrums and apparently I was the only one who could sooth him. We lived in our own fairytale-world together in which most of the time we were prince and princess. According to any adult at the time, it was the cutest and most precious thing to see us two toddlers "in love". No recordings of that though...
So, anyone else that has early childhood memories like these?
