Tires one out

Most mornings when I ask Smudge what she wants to wear for the day she usually asks for a Princess dress. I don't mind finding the most sparkly one in the closet for her, and she twirls and spins through the day as only a four year old princess can.
All the twirling and spinning does tire a princess out though and she has to rest from time to time...
until her Prince brother comes along and sings her a song to revive her.
