This sounds like a movie, except you'd likely have to age up the protagonists to make people believe it.
Four children aged 13, 9, 4, and 11 months survived a plane crash that killed three adults and then survived (apparently) on their own for 17 days in the Amazon jungle.
The children are part of the extremely small indigenous group the Huitoto. Which probably explains a lot, even if it doesn't make it less remarkable.
