Baby Sleep Schedules by Age: A Complete Guide

Total Sleep Needs by Age

The American Academy of Sleep Medicine (AASM) publishes recommended sleep durations for children based on age. These include all sleep across a 24-hour period — nighttime sleep plus naps:

Nap Transitions: When and How They Happen

Nap transitions happen as babies' awake windows lengthen and their ability to consolidate nighttime sleep improves. Each transition takes 2–6 weeks for most babies to fully adjust.

4 Naps → 3 Naps (Around 4–5 Months)

As the 4th nap becomes difficult to initiate or very short, most families shift to 3 naps. The evening catnap (often 20–30 minutes) bridges from the afternoon nap to bedtime and is the last to drop.

3 Naps → 2 Naps (Around 6–8 Months)

The third nap (evening catnap) is dropped as the baby can sustain longer awake windows and bedtime shifts earlier (often 7–7:30 PM). Signs it's time: difficulty with the third nap, resisting bedtime after 3 naps, or naps consistently short.

2 Naps → 1 Nap (Around 12–18 Months)

This is one of the most significant transitions. Signs: the morning nap is resisted or causes difficulty with the afternoon nap; afternoon nap is pushed too late and interferes with bedtime. Transition takes 4–6 weeks; some families offer an early bedtime temporarily.

Dropping Nap Entirely (Around 3–4 Years)

Most children drop their last nap between ages 3–4 years, though many still benefit from a rest period. Nighttime sleep needs remain 10–13 hours at this age.

Sample Schedules by Age Range

Newborn (0–8 Weeks): Feed-Wake-Sleep Cycles

6 Months: 2-Nap Schedule

12 Months: Transitioning to 1 Nap

Sleep Regressions: What to Expect

Sleep regressions are temporary periods of disrupted sleep that occur at predictable ages, often coinciding with developmental leaps:

• 4 months: The most significant regression. The brain restructures sleep architecture from newborn-style to adult sleep cycles. Frequent waking between cycles is normal.
• 8–10 months: Associated with increased mobility (crawling, pulling to stand) and cognitive leaps (object permanence, stranger anxiety)
• 12 months: Coincides with first steps and word development
• 18 months: Language explosion, independence push, separation anxiety peak

Regressions typically last 2–6 weeks. The best approach is to maintain your routine and offer extra comfort without creating new sleep associations that will be difficult to remove.

Establishing a Bedtime Routine

A consistent, calming bedtime routine is one of the most evidence-based strategies for improving infant and toddler sleep. Key principles:

• Timing: Begin the routine when your baby shows first tiredness cues (yawning, eye rubbing, reduced activity) — not when overtired
• Duration: 20–30 minutes is typically sufficient
• Consistency: Same sequence, same location, every night
• Wind-down signals: Dimmed lights, quieter voices, slower activities all signal sleep is coming
• Common sequence: Bath → massage → pajamas → feed → book or lullaby → crib
