[TOMT] song my mom used to sing to me

hello! my mom and i have been searching for this song for years and years. she used to have a recording of it and would sing it to me as a kid. it goes like “I will rock you, little darling, until the sandman comes to take you away.” can’t remember the rest. wish i could post an audio clip of how it goes. google is no help, i think this is a truly underground song that a small percentage of people will know. i want to remake it as a mother’s day present, but we can’t remember all the words. it’s literally just that part, haha. any help is great! (no, it’s not little darling by the diamonds)
