How much sleep does a 5-month-old need?

Between 12 and 15 hours in 24 hours. Most 5-month-olds sleep 10–12 hours at night and nap 3–4.5 hours across 3 naps during the day. Night sleep is more consolidated at 5 months than at 4 months for babies who have learned to settle independently.

My 5-month-old still wakes every 2 hours. Is this normal?

Waking every 2 hours at 5 months is more frequent than most babies need nutritionally and typically reflects a settling association rather than hunger. A baby with a dummy, feed, or rocking association will surface between each 45-minute sleep cycle and call for that association. The resolution is independent settling at sleep onset — the same approach that resolves 4-month regression waking.

How many naps should a 5-month-old have?

Three, though the third catnap may be becoming inconsistent. Most 5-month-olds take 2 longer naps and a short late-afternoon catnap of 30–45 minutes. The catnap drops naturally between 6 and 8 months. If it is becoming a battle, try pulling it 30 minutes earlier rather than dropping it — it is still needed at this age.

Can I start sleep training at 5 months?

Yes. Five months is within the developmentally appropriate window for behavioural sleep approaches. The baby's sleep architecture is fully mature, the circadian rhythm is established, and the brain is ready to form new associations. Consistency is the most important variable — whichever approach is used, it needs to be applied the same way every night and for every overnight waking.

My 5-month-old wakes at 5am. How do I fix it?

Early rising at 5 months has three primary causes: the catnap ending too late (after 5pm), bedtime being too late, or light entering the room. Ensure the room is properly blacked out — even small amounts of light are sufficient to trigger waking in a baby who surfaces between sleep cycles in the early morning. If blackout is good, check the schedule: the final wake window should be 2–2.5 hours and bedtime should be no later than 7:30pm.

Should a 5-month-old still be fed at night?

It depends on the feeding method and the baby. Formula-fed babies can typically go 6–8 hours without a feed by 5 months. Breastfed babies may still have one genuine night feed, usually in the early morning hours. More than two night feeds at 5 months is likely habitual rather than nutritional for most babies — a brief, non-feeding response is usually enough to extinguish habit feeds within 3–5 nights.

What wake windows should a 5-month-old have?

Between 1.5 and 2.5 hours. The first wake window of the day is typically the shortest (1.5–1.75 hours) and the last is the longest (2–2.5 hours before bedtime). If the baby is taking a long time to settle at nap time, the wake window may be too short. If they are fighting sleep at bedtime, the final wake window may be too short or the catnap too late.

Is teething causing my 5-month-old's night waking?

Unlikely unless the waking coincides with an eruption event. Genuine teething pain is acute and localised to the 2–3 days before and after a tooth breaks through. Persistent nightly waking across weeks is almost never caused by teething — it is caused by a settling association. Appropriate pain relief on eruption days is effective; attributing ongoing waking to teething typically delays resolving the actual cause.

What's normal at 5 months

•Three naps daily — the third is a catnap that many babies begin to resist
•Wake windows of 1.5–2.5 hours — noticeably longer than at 4 months
•Night sleep beginning to consolidate if settling is independent
•Possible teething disruption from this age onward
•Increased rolling and beginning to bear weight on legs
•Distractibility during feeds — environment matters more now
•The 4-month regression may still be active for some babies

What changed since 3.5–4 months

•Wake windows have lengthened — from 75–120 minutes to 1.5–2.5 hours
•Night sleep is consolidating for babies who have learned independent settling — stretches of 5–8 hours are possible
•The fourth catnap is dropping for most babies as wake windows lengthen
•The baby is more socially aware and responsive — the bedtime routine has more landing
•Teething may begin from 4–5 months though first teeth typically appear between 6 and 12 months

What's coming next

Between 6 and 9 months the 3-to-2 nap transition begins as wake windows continue to lengthen. This transition is typically gradual — some days 3 naps, some days 2, before settling on 2. The 6-month mark is also when solid foods begin, which does not directly affect sleep but changes the feeding schedule.

4-month regression (may still be active)

Typically 3.5–5.5 months

Some babies experience the 4-month sleep architecture change slightly later than others, or parents are still managing the effects at 5 months if no change was made to settling habits. At 5 months the mechanism is the same as at 4 months — the baby surfaces between 45-minute sleep cycles and cannot resettle without the prop they fell asleep with. The resolution is the same: independent settling at sleep onset.

Common challenges at 5 months

Third nap refusal

At 5 months the third catnap becomes inconsistent for many babies. Rather than battling it, use it as a bridge: if it happens, keep it to 30 minutes to protect bedtime. If it does not happen, move bedtime earlier by 30–45 minutes on catnap-miss days. By 6 months most babies have naturally moved to a reliable 3-nap schedule that will then begin transitioning to 2.

Night feeds when not nutritionally necessary

By 5 months most formula-fed babies can go 6–8 hours without a feed overnight. Breastfed babies may still have one genuine night feed. If the baby is waking more than twice and feeding briefly each time, the feeds are likely habitual rather than nutritional. A brief, boring response that does not include feeding is usually enough to extinguish a habit feed within 3–5 nights, while a genuine hunger feed will persist.

Early morning waking (5–6am)

Early rising at 5 months is usually caused by one of three things: the final nap ending too late, bedtime being too late, or insufficient blackout in the room. A 5-month-old's final nap should end by 5pm at the latest, with bedtime 2–2.5 hours after. Light entering the room at 5am will wake a baby who is in a light sleep phase at that time regardless of their schedule.

Teething disruption

Teething can begin producing discomfort from around 4–5 months though first teeth typically appear between 6 and 12 months. Genuine teething pain is usually localised to eruption days (2–3 days before and after the tooth breaks through). Persistent waking across weeks is rarely caused by teething — it is more likely a settling association. Appropriate pain relief on eruption days is effective; extended settling changes on non-eruption days are not.

Build your 5 months routine

Five months is an excellent time to build a routine. The circadian rhythm is fully established, wake windows are predictable, and the baby responds well to consistency. Building a solid structure now navigates the 6-month teething onset and the upcoming 3-to-2 nap transition more smoothly.
