This is the prayer I use to do with my son before bedtime.
Cast a Circle round my bed - where I lay my sleepy head, In the quiet glowing light, I sleep protected all though the night.
Prayer: Day is done, it's time for bed, Goddess bless my sleepy head. Four corner round my bed - four archangels round my bed. One at my head one at my feet and two to keep my soul asleep. Water Earth, Air and Fire - Bring gentle dreams as I retire. When the morning sun does rise, The God will bless my open eyes.
