My son is 5, and (full disclosure) mildly autistic. Lately, he's been threatening to kill himself, going as far as climbing out the window of his bedroom and threatening to jump. I expected this kind of thing when he's 15, but.... 5? I don't think he's actually serious about going through with it, but... man, he's 5. Is it just me, or is that some pretty dark **** for a 5-year-old?
