The full impact of their experience seldom takes hold until adulthood. Spontaneous recall is common, even decades later, when something triggers memory. To an adult, such a phenomenon is only one of many life occurrences. But to a child, a near-death experience is the world itself, or 'all. This colors everything children think, say, and do.
Kids face the same pattern of aftereffects adult experiencers do, but without the same options.
Among adults, the near-death experience is, for the most part, a suicide deterrent. The same cannot be said of children. Little ones do not recognize suicide as being self-destructive. Their logic is feeling based. I have'ta quit breathing to get them back.
