Since you are a parent and a musician, have you ever thought about writing a song or two specifically for children?
It just so happens that when my wife was pregnant, I asked a friend to make sure I never wrote songs about babies and parenthood. It doesn't sound like such a bad idea now, but I trust my younger self, who always found such efforts cringeworthy. So that covers songs ABOUT children. If you mean songs FOR children, like They Might Be Giants' stuff, I don't think I could pull that off.
