Bedtime songs

I swear, bedtime is what I look forward to everyday. Not only does it mean I finally get some quiet time, but I also love to sing to the kids. I can't sing worth a poo, but they don't seem to mind.
So, the reason for this post is I wanted to know what your kids favorite bedtime song is. Or of course yours if you are lucky enough to pick. 

My kids almost always pick Hush Little Baby or Rock-a-bye Baby. But, on the lucky nights that I get to choose,I love to sing Baby Mine(the song from Dumbo) or Peter Paul and Mary's Hush-a Bye ( I love that one) and one from the show MASH, but I don't know what it is called.

I love working with kids because I used to be a trained singer but your voice is a muscle and if you don't keep up with it you lose it. I sing with the kids at work and even though it might sound horrible they tell me how great I am haha. I used to love my mom singing to me and she would sing hush little baby.
