They’ll put anything you want in their mouth, but they’re just as well masters in spitting it out. Feeding 1 year olds is fun though, I give you that :P

I might be wrong, but I'd imagine a truly hungry 1 year old might manage to eat the food rather than starving.

It isn’t a matter of preference, they might not have gotten to the point where they realise it is food, or sates hunger.

And several things you don't :)

The cheetah is well known for its speed but the fastest land mammal is a toddler that was just asked “what is in your mouth?”

They found the baby bottle quite late. Maybe they managed to salvage some milk or formula from the plane.

The word „harvest“ is a particularly awkward choice given the fate of their mother…

The verb used is (now? Perhaps it was edited) "salvage".
