Dropping from 3 Naps to 2 Naps
The short answer
Most babies naturally transition from three naps to two between 6 and 9 months of age. Signs that your baby is ready include consistently fighting the third nap, taking longer to fall asleep, and being able to comfortably stay awake for longer stretches. This transition typically takes 1-2 weeks to fully settle.

By Age
What to expect by age
At this age, most babies still need three or more naps per day. Their wake windows are short (typically 1-2.5 hours), and they cannot comfortably stay awake long enough to manage on just two naps. If your baby under 5 months seems to be fighting a nap, it is more likely related to overtiredness or undertiredness rather than readiness to drop a nap.
This is the most common window for the 3-to-2 nap transition. Your baby's wake windows are extending to about 2.5-3 hours, and you may notice the third nap becoming increasingly difficult. Some babies begin refusing it outright, while others take it but then struggle with bedtime. A good approach is to start capping the third nap at 20-30 minutes and gradually pushing it later before eliminating it.
By this age, most babies have completed the transition to two naps. If your baby is still on three naps, they may be ready to drop one. Watch for signs like bedtime resistance, taking more than 20 minutes to fall asleep for the third nap, or waking earlier in the morning. During the transition, you may need to move bedtime earlier temporarily, sometimes as early as 6:00-6:30 PM, to prevent overtiredness.
By 9 months, virtually all babies are on a two-nap schedule. If your baby is still taking three naps at this age and nighttime sleep is suffering, it is time to make the transition. The ideal two-nap schedule at this age typically includes a morning nap about 2.5-3 hours after waking and an afternoon nap about 3-3.5 hours after the morning nap ends.
What Should You Do?
When to take action
- Your baby is between 6-9 months and starts fighting or skipping the third nap consistently for more than a week
- The third nap gets shorter and shorter until it becomes just a brief catnap
- Your baby seems happy and alert during the longer wake window before bedtime even without the third nap
- Some days your baby needs three naps and other days manages on two during the transition period
- Your baby seems excessively tired all day after dropping the third nap and cannot adjust after 2-3 weeks
- Nighttime sleep significantly worsens and does not improve within 2 weeks of the transition
- Your baby is under 5 months and refusing all naps or sleeping very little during the day
- Your baby is excessively sleepy, difficult to wake, or seems lethargic beyond normal tiredness
- Your baby has sudden changes in breathing, color, or responsiveness during sleep

Wake Windows by Age
Wake windows are the periods of time your baby can comfortably stay awake between sleep periods. They naturally lengthen as your baby grows, from as short as 45 minutes in newborns to 5-6 hours in toddlers. Getting wake windows right is one of the most impactful things you can do for your baby's sleep - too short and they are not tired enough, too long and they become overtired.
Baby Fighting Naps or Refusing to Nap
Nap resistance is one of the most common struggles parents face and is usually a sign that your baby is either overtired, undertired, or going through a developmental leap rather than a sign of a medical problem. Adjusting wake windows and creating a brief pre-nap routine are the most effective strategies.
Baby Only Taking Short Naps
Short naps of 30-45 minutes are the biological norm for babies under about 5-6 months of age. A baby sleep cycle is roughly 40 minutes, and it takes time for the brain to develop the ability to link cycles together during daytime sleep. Most babies naturally begin taking longer naps around 5-7 months.
My Baby Seems Overtired but Won't Sleep
When a baby becomes overtired, their body produces cortisol and adrenaline as a stress response, which paradoxically makes it harder for them to fall asleep. This creates a frustrating cycle: the more tired your baby gets, the harder it is for them to settle. Recognizing your baby's early sleepy cues and catching the right sleep window is the most effective prevention strategy.
How Long Should Baby Be Awake Between Naps?
The ideal awake time between naps (called a "wake window") increases as your baby grows. Newborns may only handle 45-90 minutes awake, while toddlers can manage 4-6 hours. Getting wake windows right is one of the most effective ways to improve nap quality, because both too-short and too-long wake times lead to poor sleep.
Is a Bath Before Bed Really Necessary?
A nightly bath is not medically necessary and some babies with sensitive skin do better with less frequent bathing. However, a warm bath can be a powerful sleep cue because the subsequent body temperature drop triggers melatonin production. If you include a bath, keep it calm and warm rather than stimulating.
