If nap time has started to feel unpredictable, you are not alone. Between 6 and 9 months, many babies are moving through changing wake windows, shifting nap needs, and the tricky transition from three naps to two. The good news is that a nap routine does not need to be strict to work well. For most families, the goal is a repeatable rhythm that helps your baby settle more easily and gives the day some shape.

Start with wake windows, keep a short and consistent wind-down, and adjust gently based on how your baby settles. The goal is a repeatable rhythm, not a rigid schedule.
What a realistic nap routine looks like at this age
Between 6 and 9 months, many babies are still changing how they nap. Some still need three daytime sleeps. Others begin to settle into two longer naps, especially as wake windows stretch.
A routine that works well usually has a few simple things in common: a fairly steady morning wake-up time, age-appropriate awake time between naps, a short predictable wind-down before sleep, and enough flexibility to handle short naps or missed naps.
That mix matters because babies this age are changing quickly. A plan that is too rigid can feel frustrating, while one that is too loose can leave the day feeling messy. The middle ground is usually the most useful.
Start with wake windows and sleepy cues
Wake windows are often the easiest way to build a nap routine. They help you work out how long your baby can comfortably stay awake before sleep starts to feel hard.
Many babies in this age range manage roughly 2 to 3 hours before the first nap, 2.5 to 3.5 hours between later naps, and a slightly longer stretch before bedtime for some babies. These are only starting points. One baby may need sleep after 2 hours and 15 minutes, while another does better closer to 3 hours. The pattern matters more than the exact number.
Look for the small signs too. If your baby seems happy and alert in the cot, takes a long time to fall asleep, or wakes quickly and does not seem rested, the wake window may be too short. If your baby gets fussy before nap time, seems wired or restless, or falls asleep fast but wakes after a short nap, the wake window may be too long.
If you are unsure where to begin, the Sleep Schedule Calculator can help you test a gentle starting rhythm based on your current wake times.

A simple shift of 10 to 15 minutes can make a bigger difference than starting over with a whole new schedule. Try one small change for a few days before deciding whether it helps.
Keep the morning wake-up and wind-down steady
A regular start to the day makes naps easier to predict. You do not need the same minute every morning, but it helps to keep the wake-up within a similar range. For example, waking between 6:30 and 7:00 most days is usually easier for a baby’s body clock than a day that starts at 8:00 and the next day at 6:00.
A steady morning also makes the first nap easier to judge. If your day feels scattered, begin with that first stretch after wake-up. Bright light, a feed, and a calm first play period often help set the rhythm for the rest of the morning.
A short pre-nap routine is usually enough. In many homes, 5 to 10 minutes is plenty if the steps stay the same. A simple routine might include closing curtains or dimming the room, a nappy change, a short cuddle, a sleep phrase or song, and placing your baby down calm and sleepy.
Keeping the same order each time helps your baby understand what is coming next. That predictability can make naps feel less of a battle, especially if your baby gets distracted easily or struggles to settle after play.

Sample rhythms for three naps and two naps
It is often easier to shape an existing rhythm than to create a new one from scratch. Watch what happens over two or three days. Which nap tends to go best? When does your baby start to look tired? Where does the day seem to unravel? Then make the routine support that pattern instead of forcing a completely new one.
Here is one sample day for a 6-month-old on three naps: wake at 7:00, nap 1 from 9:00 to 10:00, nap 2 from 12:15 to 1:45, nap 3 from 4:15 to 4:45, and bedtime at 7:15.
Here is one sample day for an 8- to 9-month-old on two naps: wake at 6:30 or 7:00, nap 1 from 9:30 to 10:45, nap 2 from 1:45 to 3:15, and bedtime between 6:45 and 7:30.
These are only examples. Your baby may nap earlier, later, longer, or shorter. A useful routine is one you can repeat on ordinary days, not one that only works when everything goes perfectly.
A small reminder: order often matters more than exact timing. Wake, feed, play, wind down, nap is a simple pattern that gives structure without making the day feel locked in.
Short naps, transitions, and small adjustments
Short naps are common at this age. They do not automatically mean the routine is wrong. Sometimes they are just part of development or part of a transition between schedules. If one nap is short now and then, you may only need to move the next nap earlier.
If short naps happen most days, it is worth looking at the bigger picture. Ask yourself whether your baby is going down too early or too late, whether the room is too bright or stimulating, whether the routine has recently changed, or whether your baby is starting to drop the third nap.
When a nap ends early, the rest of the day usually works better if you stay calm and adjust gently rather than trying to rescue everything at once. If your baby usually stays awake for around 2.5 to 3 hours but only napped for 30 minutes, the next wake window may need to be shorter. That small adjustment is often more useful than pushing through the full stretch.
Between 6 and 9 months, many babies begin moving away from three naps. This can feel awkward for a while because some days still need the third nap and some days do not. Clues your baby may be ready for two naps include the third nap becoming hard to fit in, bedtime getting pushed too late, one nap being regularly resisted, or your baby managing longer awake time more comfortably.
If sleep changes are happening alongside other developmental shifts, the Development & Behavior hub is a useful place to look at those changes in context.

Small changes are usually easier to read and easier to keep going. Try moving the first nap by 15 minutes, shortening or lengthening one wake window slightly, tightening the pre-nap routine, or bringing bedtime earlier after a rough nap day. A calmer approach usually works better than a big reset.
If you want help mapping the day, the Sleep Schedule Calculator can make it easier to see where naps may need a gentle adjustment. Some parents also like having something on paper to track what is actually happening from day to day. A simple log can make patterns easier to spot without relying on memory alone.
For that kind of support, the Baby Sleep Planner is a practical optional aid for nap timing, bedtime routine, and daily sleep notes.
