I found this song at the end of "Mother and Child" with Naomi Watts and Annette Benning. It's called "Little One" by Lucy Schwartz. It was a great movie and a great song to end it with. It particularly tugged at my heart strings because it's about a little girl growing up. I love the lyrics.
Little one Little love Little hands Look how they hold the world Stay a while Little Smile Little eyes Soon they will know the world
(Chorus) But there's no rush in getting older No use in wishing to be young Live every part of it You're at the heart of it Little one
Little one Where'd you go Once so small Look at the way you've grown Dress up dolls Playing house Those day have gone Now you've got a house of your own
