Jewish (Yiddish?) children’s song

Ok this is a long shot because I don’t remember much, but my grandmother used to sing this little song to me and my brother, it couldn’t be more than like 20 or 30 seconds. While she was singing she would take my hand in her hand and at the end would pull each finger to a sort of “boom badalah boom badalah” and the tickle the palm. Any inkling for anyone?
