My mom used say this to us all the time when we were little. She would tuck us into bed and we would say, "Mom, I love you to the moon" and she would respond "Well, I love you to the moon and back!" I've been really missing her lately.
Quote from a retired Disney princess, who was one of the first Snow Whites. I love this. When you are hugging a child, always be the last one to go. You never know how long they need it. Sometimes even us 'big kids' need those hugs , too.
