Look for the third nap being refused or pushing bedtime late across four or five days, stretch the first wake window, move the second nap into the early afternoon, and shift bedtime earlier while it settles. ![The 3-to-2 nap transition: the signs, and how to make the move](/_next/image?url=https%3A%2F%2Fcdn.sanity.io%2Fimages%2F87uht7oc%2Fproduction%2F2decdfbc248ade92ab7623cfffbe1fbd5779a145-1376x768.jpg%3Frect%3D176%2C0%2C1024%2C768%26w%3D800%26h%3D600%26fit%3Dcrop%26auto%3Dformat&w=3840&q=75) ## Key takeaways - A two-nap pattern is well established by 9–12 months; the drop from three usually happens between six and nine. - Wait for the signs to repeat across four or five days before restructuring the day. - Stretch the first window, push the second nap into the early afternoon and let it become the longer one. - Bedtime moves 30–45 minutes earlier during the transition. That is the mechanism, not a concession. - Judge the change on the 24-hour total — AASM: 12–16 hours for 4–12 months — not on the nap count. In this article 1.

It gets shorter, then it gets refused, then it pushes bedtime so late that the whole evening goes wrong. Dropping it is usually the right call — but only once you can tell a real transition from a bad fortnight. ## When it happens, and how firm that age is In the cohort data, a pattern of two naps a day is well established by nine to twelve months.[\[1\]](#ref-we) The drop from three usually happens somewhere before that, most commonly between six and nine months. That is a description of what children do, not a schedule anyone should hit — the same study found the number of naps falls with age at a correlation of about −0.5, which is a real trend and a very loose one. 9–12 months the age by which a two-nap pattern is well established — the drop from three usually lands before it[\[1\]](#ref-we) One finding is worth holding on to: total daytime sleep is a stable individual characteristic between six and eighteen months.[\[1\]](#ref-we) A baby who has always napped generously stays that way through the transition, and a baby who never has will not suddenly start. Compare your baby with themselves last month, not with the baby in the group chat. ## The signs that actually mean it - The third nap is refused outright, or takes 20 minutes of settling for a 15-minute nap. - It happens so late that bedtime is pushed past its usual time, and the night gets worse rather than better. - The first two naps have lengthened on their own — the day is consolidating. - Your baby can hold a longer window before the first nap without falling apart. ## Signs that mean something else Almost everything that looks like a nap transition in a single week is not one. Teething, a cold, a new skill being practised at 5am, a holiday, a nursery start, and the ordinary 8–10 month burst of motor development all wreck naps for a while and then stop. So does a window that has quietly become too short for a baby who now needs more awake time. Four days, not one bad afternoon Wait for the pattern to repeat across at least four or five days out of seven before you change the schedule. Restructuring the day around a single rough week is how families end up dropping a nap the baby still needed, and then spending a month rebuilding it. ### How to make the move Give it one to two weeks. The aim is a day with two solid naps, not two naps in the same places as before. 1. 1 Stretch the first window a little Add 10–15 minutes before the first nap every few days. That first window is what makes room for the rest of the day. 2. 2 Push the second nap later Aim for a second nap that starts early afternoon and is the longer of the two. The morning nap gradually becomes the shorter one. 3. 3 Cap the morning nap if it eats the afternoon If the morning nap runs long and the afternoon one collapses, wake your baby from the morning nap at around an hour. 4. 4 Move bedtime earlier — properly earlier On two naps the last window is doing far more work. An earlier bedtime is not a treat during this transition, it is the mechanism that stops the whole thing falling apart. 5. 5 Keep one bridge nap in reserve On the days it fails, a short late nap in the pram or the carrier — then an earlier bedtime anyway — is better than pushing an exhausted baby to bedtime on principle. ## What the day looks like before and after On three naps On two naps Wake 07:00 07:00 Nap 1 08:45–09:45 09:15–10:15 Nap 2 12:30–13:30 13:00–14:30 Nap 3 16:00–16:30 — Bedtime 19:30 18:45–19:00 A worked example, based on a 7am start Note where the slack goes: the last window is the longest of the day, which is the same principle behind [wake window stacking](/learn/sleep/wake-window-stacking). If you would rather work from your own baby's ages and times than from an example, the [wake window calculator](/tools/wake-window-calculator) will do the arithmetic. Early bedtime is the whole trick During a nap transition, bedtime moving 30–45 minutes earlier is normal and temporary. Trying to hold the old bedtime is what turns a two-week transition into a month of 5am wake-ups. ![](/_next/image?url=%2Fimages%2Fnap-plan-icon.webp&w=256&q=75&dpl=dpl_HDQuuA58EiAncPne4fumhEvNhdFC) Dalo Sleep See the pattern instead of remembering it Dalo Sleep logs naps and wake windows, so "is the third nap actually failing?" becomes a question you can answer from a week of data rather than from the last bad afternoon. [Dalo Sleep](/apps/dalo-sleep) ## How long the messy part lasts Usually one to two weeks, with a handful of days in the middle where two naps are clearly not enough and three no longer fit. Those are early-bedtime days. Expect it to look like it is not working around day four; that is normally the point at which it starts to. ## Judge it on the 24-hour total The nap count is a means, not the goal. What matters is the total across the day and night: the AASM consensus recommends 12–16 hours per 24 hours for infants aged 4–12 months, including naps, and says nothing about how that total should be divided.[\[3\]](#ref-aasm) If your baby is landing in that range, waking cheerful and making it through their windows, the transition is working even on a day the schedule looks nothing like the table above.[\[5\]](#ref-nhs) It is worth knowing how thin the evidence is under all nap advice. A systematic review of napping and child development from birth to five years found 26 studies, all observational and all graded low quality.[\[4\]](#ref-th) Nap counts by age come from cohorts describing what children did, not from trials showing what works — which is exactly why your own baby's pattern beats any published schedule.

Most commonly between six and nine months, and cohort data show a two-nap pattern well established by nine to twelve months. The range is wide and the age is not the deciding factor — a baby refusing the third nap at seven months and a baby still taking it at ten are both ordinary. Should the morning or the afternoon nap be the long one? The afternoon one, in most schedules. A long morning nap tends to eat the afternoon nap and leave a very long final stretch before bed. If the morning nap regularly runs past an hour and the afternoon one collapses, capping the morning nap usually fixes both. My baby needs the third nap some days and not others. What do I do? That is what the transition looks like from the inside, and it can last a couple of weeks. Keep the third nap available as a short bridge on the days the first two are poor, and move bedtime earlier on the days it does not happen. Both tools are temporary and both are normal. Will dropping a nap make night sleep worse? Briefly, yes — overtiredness during the changeover shows up as early waking and harder settling. That is why bedtime moves earlier for a fortnight. If night sleep is still worse after two or three weeks on the new pattern, the day is probably not settled yet rather than the nap being dropped too soon. ![Dalo Sleep](/_next/image?url=%2Fimages%2Fnap-plan-icon.webp&w=128&q=75&dpl=dpl_HDQuuA58EiAncPne4fumhEvNhdFC) Get it on your phone Dalo Sleep [Dalo Sleep](/apps/dalo-sleep) Part of [Baby sleep schedules and wake windows: 0–24 months](/learn/sleep/baby-sleep-schedules-and-wake-windows) ## Keep reading [ ![](/_next/image?url=https%3A%2F%2Fcdn.sanity.io%2Fimages%2F87uht7oc%2Fproduction%2F578eb7b0a50d77606876dc160b56e3e46e07dd4a-1376x768.jpg%3Frect%3D7%2C0%2C1363%2C768%26w%3D440%26h%3D248%26fit%3Dcrop%26auto%3Dformat&w=3840&q=75) ### Wake window stacking: why the last one should be longest Wake windows across a day are not equal.
