Bedtime prayers

I've been wanting to start bedtime prayers with Bo.  I know it's early and he won't be able to say them, but I at least want him to get used to the idea and hearing them.  Growing up I said "Now I lay me down to sleep", but I have a problem with the "if I should die" part so I searched and found a version that I just love.  I do this with Bo after we read his story and on occassion he'll even put his hands together so we're getting there!

Now I lay me down to sleep,

I pray the Lord my soul to keep.

May angels watch me through the night.

And keep me safe til morning light.

~Amen
