On an overnight flight my nearly 3-year-

First, the name for the night you had

That's a night terror (sleep terror), not a nightmare — and the difference is why what you tried didn't work. Terrors happen out of the deepest non-REM sleep, in the first third of the night, when she's asleep, not awake: screaming, thrashing, eyes open, and she usually won't recognise you or remember it. Nightmares come *later*, she wakes up, and she can tell you the dream. Terrors are most common between 3 and 8, often run up to ~15 minutes, and can repeat the same night.

What causes them (the levers you can actually move): being very tired or unwell; a disrupted deep-sleep block — which is exactly what an overnight flight, a late nap cut-off and a new bed all do; noise or needing the toilet pulling her up out of deep sleep; and stress or a frightening thing. Being family-history common, they usually grow out of it.

So this was schedule mismatch + sleep debt, not a habit and not something you caused.

1) What you tried vs what to do instead

For your own head, on the flight specifically: she cannot hurt you if the kick has no room to land — that's the whole in-flight job, and it's the part you can control.

Today / before the next trip (routines, food, nothing bought):

• Protect the nap; move it earlier, don't cut it. Her 3–5 band is 10–13 h across 24 h including naps (AASM 2016 consensus). Sleep debt the night before a trip is the single strongest trigger.

• Keep the chain: pyjamas → teeth → one or two books, screens off about an hour before. Same order every night, including away. Jet lag disturbs children as it does adults.
• Naps on arrival: 15–20 minutes only if she's sleepy in the day. A long daytime nap stalls the whole shift.

The weekly anchor (one sentence, no answer needed): Pick the one wake time on the destination calendar that cannot move, get her up at it every day including the day with nothing booked, and let bedtime follow sleepiness instead.

What success looks like in 24 hours, honestly: not zero episodes — a shorter episode, an easier one to get through, and her waking at the anchor time. Most children grow out of this. I can't promise a number of quiet nights.

2) Constraints and the avoid list

• No melatonin for her — no milligrams, no "just a little," no timing chart. Timed melatonin is a clinician tool; nothing here doses a child.

• No mystery powders, gummies, "sleepy" teas, or anything bought online for her sleep or calm.
• Don't change or add any medication — including anything you already give her. Some medicines can worsen terrors; that call belongs to her prescriber or pharmacist.
• Don't withhold the nap to "save" night sleep. That's the trade that sets up the next episode.
• Don't let a short stay become an adaptation project — under about two days away, keep home-base sleep, meals and light rather than fighting the clock.

• If you're driving after any of this: sleepy driving is a stop, not a dose. Arrange the ride or the stop; the clinician or licensing authority decides fitness to drive.

3) Red flags — when to stop DIY

Stop and get her seen by a doctor if:

• Terrors that start after age 5, persist past age 12, or become frequent, or come after an upsetting or frightening event.

• She seems hard to wake, unusually sleepy in the day, or her behaviour changes during the day.
• The episode happens while she's awake, or comes with fever, marked twitching, or confusion that doesn't clear.
• Pauses in breathing, gasping or snoring, or turning blue/pale in sleep — that's a different conversation entirely; stop lifestyle advice and take it to a clinician.

• Emergency care now: an episode where she or you are actually injured, or a breathing pause or colour change.

Decision tree — screenshot this:

```
Screaming + thrashing + eyes open + not awake?
├─ Yes → terror. Don't wake her. Clear the space. Low light, low voice, one hand on her.
│ ├─ Safe space possible → wait it out (up to ~15 min), then back to sleep
│ └─ Can't make it safe → hold position away from edges, ask a second adult
└─ No → is she AWAKE, and does she remember a dream?
├─ Yes → nightmare. Comfort, stay, that's it.
└─ No / hard to wake / breathing pause / blue / daytime collapse / new after age 5
→ doctor. Not tonight's routine problem.
```

Two things that are the clinician's, not mine: anything timed or prescribed (melatonin included) on a trip, and sleep still broken well past the adaptation window for the zones you cross. Those go to `family-doctor`.
Hand off: tonight's moves and the wake time are yours; anything prescribed is your pediatrician's — I'd take a night log and the episode pattern to them rather than try another light trick.

Record or clinic this week: this was a one-off bad night on a red-eye, so no clinic trip needed yet — but if she does this several nights a week at home, say the word and I'll keep a short night log (night, time it started, how long, how she was the next morning) for you to hand to the pediatrician.

One thing I can't see from here: what time your flight lands versus her usual nap. Tell me the departure and arrival times and I'll set the nap and wake anchors to actual clock times.
