Here’s the twist: most countries don’t have a magic age. The law is a vague, shrug-happy monster. Only three U.S. states have a legal minimum age for leaving a child home alone. Illinois says 14. Maryland says 8. Oregon? They just say “reasonable discretion.”
Translation: you can leave an 8-year-old in Oregon but risk jail in Illinois. Wild, right? The UK? No official age, but the National Society for the Prevention of Cruelty to Children (NSPCC) says most kids under 12 aren’t ready. Most isn’t all. It’s a personality test, not a rulebook.
