"The auld woman gaed tae waken the maid"
And it doesn't need to reffer SPECIFICALLY to a child. Variants of tales can be very far apart in details, I remember reading a book about the myth of Prometheus, it seems they have some 1000 versions in Caucaz, and some of them don't even mention fire - the guy gets to be a hunter or a shepperd. The common part is that he is finally crucified(?) for fooling around with the gods.
