A trip almost always knocks a child's sleep off course: a new place, a different time zone, the journey itself. You will not avoid that entirely, but you can soften it a great deal. Here is how to prepare, get through the flight and come back to the schedule without long-lasting consequences.
A child falls asleep on familiar cues. If you recreate the usual sleep setting in a new place, adjusting will go more easily. Put together a "travel sleep kit":
The benchmark is roughly one day of adjustment for each hour of difference. A difference of 1–2 hours is usually barely felt. From 3 hours upwards it is worth preparing in advance.
Often the simplest thing is to live by local time straight away and just get through a couple of shifted days. There is no need to prepare specially.
Start shifting the schedule in advance, towards the coming time zone, at the same pace as always — by 15 minutes every 2–3 days. Over the 3–5 days before the flight that adds up to about half an hour: with a difference of 3 hours or more you cannot move the whole schedule in advance, and the main rebuild will happen once you are there.
| Situation | What to do |
|---|---|
| Woke in the middle of the night wide awake (daytime by the old clock) | Dim, quiet, no games or screens; behave as you would at night |
| Dropping with tiredness during the day, earlier than usual | A short nap plus more light, to stretch to the local bedtime |
| Cannot fall asleep in the evening (daytime by the old clock) | Blackout, white noise, a calm, long routine |
Adjusting back follows the same rules. At home you have an advantage — familiar surroundings — so the rebuild is often faster. For the first 2–3 days keep the schedule especially firm: a stable wake-up time and plenty of daylight give the body clock its "anchor". If new habits appeared during the trip (rocking, sleeping in your bed), return to the home scheme gently — the sooner, the easier.
Roughly one day for each hour of difference. A difference of 1–2 hours is barely felt, while at 3 hours or more it makes sense to start shifting the schedule in advance — at the same pace as always: by 15 minutes every 2–3 days. Over the 3–5 days before the flight that adds up to about half an hour; the rest is picked up once you are there, and the main lever there is daylight.
Put together a "travel sleep kit": a white noise device, the usual sleep sack, the favourite toy (after one year), something to black out the window, and everything you need for the same routine (the same books, the same lullaby). Familiar cues help a child fall asleep in unfamiliar surroundings.
Once you have arrived it is usually more effective to live by local time immediately — in meals, naps and bedtime — helping yourself along with light. A gradual shift is useful beforehand, while still at home, in the days before the trip. Dragging out the switch on the spot with a "halfway" schedule is not worth it — it makes the adjustment longer.
Return calmly to the home scheme: a firm wake-up time, plenty of daylight, the familiar routine, bedtime in the usual window. Expect a setback of 3–7 days. If new falling-asleep habits have appeared, wind them down gently straight away — at home, in familiar surroundings, that goes faster.
Baby Sleep Planner adapts the plan to your child from just 4 days of the diary: it works out wake windows and today's bedtime by age and by your child's own rhythm. The first observations about your child appear from day 10, and the analysis of schedule changes from day 14.
