Bedtime Routine Tips
Screens off 1 hour before bed
Blue light from devices delays melatonin production, pushing sleep time later.
Warm bath routine
A warm bath 60–90 minutes before bed triggers the body's natural cooling response which aids sleep onset.
Bedtime story
Reading together calms the mind and creates a reliable sleep cue. Even older children benefit from quiet reading time.
Cool, dark bedroom
The ideal sleep temperature for children is 16–20°C. Use blackout curtains, especially in summer.
Consistent schedule
Same bedtime and wake time every day — including weekends — is the single most powerful tool for better sleep.
No sugar or caffeine after 3pm
Cola, energy drinks, chocolate, and sweets can all delay sleep. Even fruit juice contains natural sugars that raise alertness.
Bright light in the morning
Morning sunlight resets the circadian clock. Open curtains immediately after waking to anchor the body's sleep schedule.
School prep the night before
Reducing morning stress means children can wake more gradually and calmly — improving the quality of their sleep window.

Frequently Asked Questions
Children aged 3–5 need 10–13 hours of sleep per night according to both the NHS and the AAP. For a 5-year-old waking at 7am, the ideal bedtime is between 6pm and 9pm, with 7pm–7:30pm being optimal for most children at this age.
For a 10-year-old waking at 7am, the recommended bedtime is 8pm–10pm, giving 9–12 hours of sleep. On school nights, 8:30pm is a practical target for most families at this age. Consistency matters more than the exact time.
First, check the timing — if your child is overtired or not tired enough, neither will work. Move bedtime 15 minutes earlier or later and observe. Then audit the routine: screens off 1 hour before bed, consistent sequence of events (bath → pyjamas → story → lights out), and the same time every night including weekends. Most sleep issues in children resolve within 2–3 weeks of a consistent routine.
Key signs include: difficulty waking in the morning, falling asleep in the car or during the day, irritability or emotional outbursts, poor concentration at school, hyperactivity (overtired children often become hyper rather than tired-looking), frequent illnesses, and weight gain over time. Many children's "behavior problems" are actually sleep deprivation.
Yes. Teenagers need 8–10 hours — more than most adults. Adolescent biology also shifts the circadian rhythm later, making it genuinely harder for teens to fall asleep before 11pm. This is a physiological reality, not laziness. Early school start times are a significant public health issue for this reason. Where possible, allowing teens to sleep later at weekends and on holidays is beneficial.
Under 3: naps are essential. Ages 3–5: one nap of up to 90 minutes is fine if needed. Over 5: daytime napping generally isn't needed and can interfere with night sleep. If a school-age child is regularly napping, they're likely not getting enough sleep at night — address the night schedule rather than encouraging the nap.
