I found this a while back. I wrote it several years ago for the girls, and as I read it, I realized that God is answering this even when I forget to ask. He is faithful and true, even when I am not paying attention!
Father, bless their sleep, my prayer
Guard their minds, their souls, their cares
Keep them still throughout this night
Wake them with the morning light
Bind their fears and grant Your peace
May Your mercy never cease
Stay with them all of their days
Bless them Lord, is all I pray
Lord of Hope, of Grace, of Love
Look on these girls from up above
Smile on them Lord, shine through them too
May they be bright lights, shining for You
May they know the love you gave
By sending Your Son, our souls to save
Let them share Him faithfully
And allow others Your love to see
Father, bless their sleep this night
Keep their spirits shining bright
Thank You for this day we’ve spent
And for these girls who are heaven-sent.
