I heard a great song a few years on the radio, that sounded like it might have been by Sally Rogers (but maybe not?). It was a mother singing about impossible questions here young child asked her. I don't remember all the verses, but the last one went something like "Why can't a cow have chickens / oh why oh why oh why / oh why oh why oh why oh why / sleep, baby sleep.

Anyone know who wrote it, or where I can get the lyrics on the web?

Thanks!
