My son doesn't throw very many tantrums (not yet anyway) and when he does, they're usually over very quickly. HOWEVER, he threw the most epic and longest tantrum in his 2 years of life just an hour ago. He woke up from his nap way too early and was balling his eyes out and jerking his body for literally 20 minutes straight. I thought he was injured or something. After 20 minutes, he knocked out and went into a deep sleep.

That's definitely the longest tantrum he's ever thrown. How long do your LO's tantrums usually last? What's the longest one so far?
