You mention Hansel and Gretel; you’re not alone w/that! I thought of that too, so did some other posters, and it’s almost exactly the same. Another one would be “Jungle Book”, with “Mowgli”, the little boy left to be raised by wolves (at least partly)”The Hunchback Of Notre Dame”, and “Oliver Twist”!
A lot of these stories were inspired by these situations of parents leaving children behind by death or abandonment, and in dangerous places! Of course in Oliver Twist’s case, the mother gave birth, died, and left him in the care of the people in the orphanage or workhouse. She didn’t just leave him out in nature. I also thought of Romulus and Remus and Tarzan,as well!
I also think that the Hunchback was like Oliver T. in that they both were abandoned at a church or orphanage or some other place, not in the wild.
