The short answer
AASM recommends 12–16 hours of sleep per twenty-four hours, including naps, for babies aged four to twelve months. At six months, the balance between night sleep and naps varies, and night feeds may still be needed. Consider rest, feeding, growth, and alertness rather than aiming only for an uninterrupted night.

Keep in mind
- The 12–16-hour reference includes both night sleep and naps.
- Use sleep cues alongside the wider feeding and wellbeing pattern.
- A calm routine can be flexible rather than a fixed timetable.
- Act on warning signs before completing a diary.
How might night sleep and naps fit together?
Some babies develop a longer first stretch at night, while others wake for milk, reassurance, or because of discomfort or illness. “Sleeping through” is not a single universal number of hours.
Naps may remain in several parts. Some babies consolidate them while others need more opportunities; do not force a two-nap schedule or stop feeds just because of age.
How can you notice rest and tiredness?
Feeding, interaction when awake, and growth over time provide useful context. Yawning, looking away, slowing down, or fussing may suggest tiredness.
Do not deliberately keep your baby overtired to meet a schedule, but do not interpret every cry as a sleep cue either: hunger, temperature, discomfort, and a need for contact can look similar.
What can a calm routine include?
Try a short familiar sequence: dim lights, a diaper and clothing change, a feed, and a quiet song or book. The aim is predictability rather than forced independence.
Keep night care quiet and daytime opportunities for normal light and interaction. A repeated sequence can be more manageable than an exact clock time.
How should the sleep space be arranged?
Always start sleep on the back on a firm, flat approved infant sleep surface. Keep pillows, blankets, bumpers, toys, and positioners out. Once your baby reliably rolls both ways independently, they need not be repeatedly turned back, but keep starting sleep on the back.
Use a separate sleep space, with room-sharing for at least the first six months. Sofas and armchairs are especially hazardous if you fall asleep while feeding or comforting; plan how to return your baby safely to their own sleep space.
When can a sleep diary help?
A few days of notes on sleep, naps, waking, and feeding can reveal the pattern. It is not a scorecard: seek advice promptly for reduced intake, fewer wet diapers, fever, or altered wellbeing, and call 911 for severe breathing difficulty, blue/gray color, stopped breathing, or inability to wake.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Severe breathing difficulty, stopped breathing, blue/gray color, or inability to wake: call 911.
- Sleepiness interfering with feeding, fewer wet diapers, or unusual reduced responsiveness needs prompt assessment.
- A sudden sleep change with fever, pain, repeated vomiting, or worsening wellbeing needs medical advice.
