My teenage daughter loves me dearly but does not love me posting pictures of her without her prior permission. She is not likely to give permission for this one, but it warms my Mama heart. Seriously. Is anything cuter than my girls harmonizing during Family Night? The answer is baby pandas. But other than that (and, well, puppies,) Sophie and Kate and a guitar get my vote.
If I was REALLY brave (and stupid,) I would post a video of them singing. Because that beats pandas, puppies, otters, AND kittens. But I value my life, so you will have to just imagine.
