In just a few weeks, our clocks spring forward, and our families will be impacted for weeks: earlier sunsets, later sunrises, and a few groggy mornings as everyone adjusts. Understanding what it is and how to help ourselves can be really helpful. So let’s dive in and dissect what is happening. The root cause is simple — our bodies run on circadian rhythms, internal 24‑hour clocks that rely heavily on light cues. Understanding how those rhythms work and using practical strategies can make the transition smoother for kids (and exhausted parents).

How light shapes our internal clock

Circadian rhythms are regulated by a region in the brain known as the suprachiasmatic nucleus. Light hitting the retina sends signals into our body to tell us whether it’s time to be awake or to prepare for sleep. Morning light suppresses melatonin (the sleep hormone) and raises alertness; evening light delays melatonin release and shifts sleep later. Artificial light — screens, bright indoor lighting — can trick the brain into thinking it’s still daytime, especially in children whose circadian systems are more sensitive. 

Why does the time change affect families?

When clocks move forward, the day’s light/dark pattern shifts relative to our internal clocks. Kids may wake up “earlier” by the clock but feel like it’s still nighttime biologically, causing crankiness, difficulty falling asleep, and disrupted naps. Younger children and toddlers, who depend on consistent schedules, often show mood changes, reduced attention, and increased night wakings. Even short sleep deficits accumulate: less restorative sleep can affect behavior, memory, and immune function.

Practical strategies to ease the shift

Shift schedules gradually

Start adjusting bedtime and wake time 10–15 minutes earlier every two to three days in the week leading up to the change (or after, if you’re short on time). Small, consistent shifts are easier for kids’ bodies to accept than a sudden one‑hour jump.

Prioritize morning light

Expose children to bright morning light as soon as possible after waking — open curtains, sit on the porch, or have breakfast outside. Morning light helps reset the circadian clock earlier, making it easier to fall asleep earlier that night. This, by far one of the most untapped practices to adjust the arcadian system for kids.

Dim evenings and limit screens

Two hours before bedtime, reduce bright overhead lights and use warm lamps. Avoid screens (tablets, phones, TVs) close to bedtime; the blue light they emit suppresses melatonin. If screens are necessary, enable blue‑light filters and keep devices at low brightness.

Keep consistent routines

Maintain predictable wind‑down rituals: bath, storytime, soft music, and a calm activity. Routine cues help the brain understand it’s time to sleep, even if the clock has changed. Keep nap timing consistent for younger children, adjusting by small increments if needed.

Manage daytime naps and activity

If a child is extra sleepy in the early afternoon, allow a short, restorative nap but keep it earlier in the day to avoid disrupting nighttime sleep. Use active, outdoor play in the late afternoon to promote tiredness by evening.

Use sleep‑friendly sleepwear and environment

A cool, dim, and quiet bedroom supports sleep onset. Breathable, thermoregulating sleepwear like this 2 piece Merino Wool Pj Set can help maintain comfort through temperature shifts as the seasons change. Consider blackout curtains for earlier bedtimes and light alarms for gentle wakeups if needed.

Stay patient and flexible

Most children adjust within a few weeks. Expect some regressions and plan for extra short naps or earlier bedtimes during the adjustment period. Keeping a lighter schedule during these weeks will make your lie easier during this transition. 

By leaning into light management, gradual schedule shifts, consistent routines, and sleep‑supportive environments, families will be able to get through this difficult time of the year.
