lullaby lullaby, my sweet and tender child, lullaby my little lamb

Its a very common melody. I've known it for as long as I can remember, however only the first few words even exist anymore. I have a very broken family. The only blood family I have are my little brother and sister. We all know this melody. But I'm the only one who remembers words. We'd all like to know if there's any more, or maybe we're just dreaming of wishes.

Lullaby Lullaby
my sweet and tender child
Lullaby my little Lamb

That's all the clue we have. That and the melody, but I don't know how to convey the melody and haven't found a similar song in a very long time. Does anyone have any idea what it is from?
