The science behind better sleep.
Tiny Rhythm blends age-based sleep needs, consistent routines, and sleep-pressure timing into guidance that feels calm, simple, and realistic.
A day of rhythm
Aligning sleep with natural circadian cues supports longer, more restorative sleep.
What we build around
Age-appropriate sleep
Sleep needs shift quickly in the first year. We adapt guidance to your baby’s age and development — including corrected age for early arrivals.
Circadian rhythm
We align sleep opportunities with your baby’s natural body clock and the daily light–dark cycle.
Responsive routines
Consistent, calming routines reduce friction and help your baby feel safe, seen, and ready for sleep.
Sleep needs change fast in the first year.
Typical total sleep in 24 hours, including naps.
Ranges are averages drawn from the National Sleep Foundation (Hirshkowitz et al., 2015), the AASM consensus (Paruthi et al., 2016), and pediatric guidance on typical night stretches. Follow your baby’s cues and context.
Why rhythm matters
Research suggests small, consistent changes add up to better sleep.
In young children, bedtimes placed too close to the body’s evening melatonin rise were associated with longer time to fall asleep (r = 0.72) and more bedtime resistance. Research suggests aligning sleep timing with your child’s building sleep pressure and body clock can make settling easier.
Among more than 10,000 families, infants and toddlers with a nightly bedtime routine had parent-reported sleep problems roughly half as often as those with no routine (23.3% vs 47.2%), and the benefit grew the more consistently the routine was followed. This is an association, not proof of cause.
In toddlers around 18 months, later nap end-times were associated with shorter nighttime sleep (r = −0.31) and later bedtimes (r = 0.52). Research suggests earlier, appropriately timed daytime naps may support longer, more consolidated night sleep.
