"Is this normal for their age?" is probably the most repeated question about baby sleep. Here's a full month-by-month reference chart, to have a real point of comparison — without replacing your own baby's rhythm.
Sleep chart by month
| Age | Naps | Total sleep/day | Longest night stretch |
|---|---|---|---|
| Newborn (0-6 weeks) | 4-5 (irregular) | 15-17h | 2-3h |
| 2 months | 4-5 | 14-17h | 3-4h |
| 3 months | 3-4 | 14-16h | 4-5h |
| 4 months | 3-4 | 14-16h | 4-5h |
| 5 months | 3-4 | 13-15h | 5-6h |
| 6 months | 2-3 | 13-15h | 6-7h |
| 7 months | 2-3 | 13-15h | 6-8h |
| 8 months | 2-3 | 12-14h | 7-8h |
| 9 months | 2 | 12-14h | 8-9h |
| 10 months | 2 | 12-14h | 8-10h |
| 11 months | 2 | 12-14h | 8-10h |
| 12 months | 2 (or transitioning to 1) | 12-14h | 9-10h |
These are reference ranges, not a test to pass. Some babies naturally sleep more, others less, within a perfectly healthy range — what matters most is the general trend, not comparing a single day against the chart.
How a typical day shapes up, month by month
- 0-3 months: no fixed schedule — the baby eats and sleeps guided by hunger and sleepiness, in short, unpredictable cycles.
- 4-5 months: more regular patterns start to emerge, with 3-4 naps spread across the day.
- 6-8 months: a 3-nap schedule usually settles in and then drops to 2, with a long midday nap anchoring the day.
- 9-12 months: 2 more stable naps (morning and afternoon), with night sleep already concentrated into one long stretch.
What age does a baby sleep through the night?
It varies a lot from baby to baby, but there's a general pattern: many start doing long nighttime sleep stretches (5-6 hours in a row) between 3 and 6 months, and some don't consolidate a full night until closer to a year. "Sleeping through the night" for babies usually means that — a long stretch without waking, not necessarily 12 hours straight like an adult.
Two factors that tend to speed up or delay that milestone: whether the baby is still waking for real hunger (see when night weaning makes sense), and whether their daytime naps are well covered — an overtired baby during the day sleeps worse at night, not better.
Why this chart is only the starting point
Every baby has their own temperament, their own circadian rhythm, and their own way of moving through each stage. A 6-month-old still taking 3 naps, or a 9-month-old who's already down to 1, can be perfectly within the expected range. The chart is here to orient you, not to trigger alarm if your baby doesn't fit exactly into one row.
