I typically just make them up on the go but I feel like good night moon counts! :)
Depends on how strict you wanna be.
My mom would play Queen's we will rock you for me when I was still a baby, and well into the point I was old enough to remember.
Oh damn, I woke up my wife laughing at that. That's brilliant
I’ve sung “Sweet Child o’ Mine” to my son (with minor lyric changes, she->you for instance) in a soft voice almost every night since he was born… three and a half years now.
My son used to only fall asleep if we played Voodoo by Godsmack.
