Frequently asked questions
How many days does jet lag last with kids?
About one day per time zone flying east and a little less flying west. A 2–3 day head start shortens that.
Which direction is worse for jet lag?
East, because the body clock has to move earlier. For 10+ hours east, delaying the long way around is often faster.

Not medical advice. General sleep and travel guidance based on published circadian research. Ask your doctor or pediatrician about melatonin or other supplements, pregnancy, medications or health conditions. Never give melatonin to babies or toddlers.
