Transitioning My Toddler to One Nap
The short answer
Most toddlers transition from two naps to one nap between 14 and 18 months of age. The transition typically takes 2-4 weeks and can be bumpy — expect some overtired days. Signs your toddler is ready include consistently fighting the morning nap, taking so long to fall asleep for one nap that the other is affected, or napping well but fighting bedtime. The single nap usually lands around midday and lasts 1.5-3 hours.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
12-14 months
While some toddlers show signs of nap resistance around 12 months, most are not truly ready for one nap until 14-18 months. The 12-month sleep regression, developmental leaps, and new physical skills (walking) can cause temporary nap disruptions that resolve on their own. If your toddler fights one nap for a few days but still seems to need it (gets cranky and overtired without it), wait before making the switch. Dropping a nap too early often leads to chronic overtiredness and worse sleep overall.
14-18 months
This is the most common window for the two-to-one nap transition. When you are ready to make the switch, gradually push the morning nap later by 15-30 minutes every few days until it lands around 12:00-1:00 PM. During the transition, temporarily move bedtime 30-60 minutes earlier to prevent overtiredness. Some parents use a "one nap / two nap" alternating schedule for a few weeks — offering two naps on days when their toddler wakes early or seems especially tired, and one nap on other days.
18-24 months
By 18-24 months, most toddlers have fully settled into a one-nap schedule. The single nap typically lasts 1.5-3 hours and occurs in the early afternoon. If your toddler is still on two naps at 18+ months and is sleeping well, there is no need to force a change. Every child is different. If the transition has been rocky and your toddler seems chronically overtired (frequent tantrums, early morning waking, nighttime wake-ups), consider whether the nap timing or length needs adjustment.
What Should You Do?
When to take action
- Your toddler is inconsistent during the transition — some days needing two naps, other days doing fine with one
- Your toddler is crankier than usual in the late afternoon during the first 2-4 weeks of the transition
- Your toddler's single nap varies in length from day to day as the schedule settles
- The transition takes several weeks to fully complete
- Your toddler dropped to one nap before 12 months and seems chronically overtired
- Your toddler's total daily sleep has dropped significantly and they seem exhausted, irritable, and are having frequent meltdowns
- Your toddler cannot stay awake long enough to make it to a midday nap and falls asleep in the car or at meals
- Your toddler is excessively sleepy during the day despite adequate nighttime sleep, which could indicate an underlying medical issue
- Your toddler has new-onset snoring, gasping, or breathing pauses during sleep that are affecting sleep quality
- Your toddler is so overtired that they are having frequent injuries from impaired coordination

Signs My Toddler Is Ready to Drop a Nap
Most toddlers transition from two naps to one between 12-18 months, and many drop their final nap between ages 3-4, though some children nap until age 5. Signs that your toddler is ready to drop a nap include consistently taking a long time to fall asleep for naps, napping well but then fighting bedtime, or skipping naps without becoming overtired. Nap transitions are gradual and often take 2-4 weeks to settle.
18-Month Sleep Regression
The 18-month sleep regression is driven by explosive language development, increasing independence, separation anxiety resurgence, and possibly the transition from two naps to one. Your toddler's vivid imagination may also lead to new nighttime fears. This phase typically lasts 2-6 weeks with consistent routines.
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.
How Long Should the Bedtime Routine Be?
An ideal bedtime routine for babies and toddlers is 20-30 minutes. Shorter routines may not give enough time to wind down, while routines longer than 45 minutes can become a stalling tactic. Consistency in the routine order matters more than exact length.
