A female of child bearing age, or maybe even a little younger, might attempt to take care of it, but would be unsuccessful. The first problem would occur immediately when a gorilla attempted to pick it up. Non-human primates are generally born ready to go, at least when compared to humans.

Not that they’re up and running around, climbing trees and trying to forage for food, but they can at least hold their own head up immediately, and limited mobility, clumsily crawling, within a few hours. A human baby is incapable of holding its own head up for the first several months.

Beyond that, there’s the clinging thing, something a human baby would never be able to do. Then there’s the rate at which we develop in regards to their development.

For the most part, they develop very quickly, and are generally self sufficient by around one year of age, relying on the silverback only for protection, and the mother for teaching and maybe an occasional nursing. A human baby would also never be able to survive on what’s available to a gorilla in the wild, nor would it even be able to eat it in the first place.

As others have mentioned, gorilla milk and human babies might not even be compatible. Also, when it’s time to go on the move in search of new feeding opportunities, the baby wouldn’t be able to follow along or even cling to a gorilla, so it would most likely be abandoned where it is.

A human baby would definitely die quickly if left in the care of a gorilla, despite its best efforts to care for it and generally gentle disposition. There’s also that possibility that a gorilla would view the baby as a possible threat.

It may or may not understand that a human baby is 100% completely harmless, and act accordingly. There are just way too many factors in play against a human baby being cared for by a gorilla, and not one single thing in the human’s favor.

I’d be surprised if a human baby survived 15 minutes in the care of even the most nurturing and caring of gorillas, regardless of how gentle it tried to be.
