That's a broad category! I started with songs of contact with the two generations and went on from there. Peggy Seeger 'Little Girl Child' Murray McLauchlan 'Child's Song' (Tom Rush sang it - where's he now?) Gordon Lightfoot 'Sit Down Young Stranger' Utah Phillips 'Daddy what's a train?' Ewan MacColl "My Old Man", "Joy of Living" "When I was young, I had no sense, I bought a fiddle for 18 pence, The only tune that it would play was over the fields and very far away" "All Used Up", various songs about aging An Sean Bhean Bhocht, Four Green Fields (Tommy Makem), The Bold Fenian Men, Daniel O'Connell (allegorical use of the old woman) the Keech in the Creel, the Spinning Wheel, Casadh an t-Sugáin, the whistling Thief -and many many more songs where parents are at odds with their children over courtship millions of lullabies Somebody else has done this: I just checked and the DT has categories for @age, @youth, @child
