Dropping from Two Naps to One
The short answer
Most babies transition from two naps to one between 12-18 months. Signs include consistently fighting or skipping the second nap, taking very long to fall asleep for naps, or bedtime becoming a battle. The transition usually takes 2-4 weeks and some crankiness is normal during the adjustment.
By Age
What to expect by age
Some babies flirt with dropping a nap around 10-12 months, but this is usually a false alarm caused by a developmental leap or the 12-month sleep regression. Most babies still need two naps at this age. If your baby occasionally refuses a nap, try offering it a bit later rather than dropping it entirely.
This is the most common window for the 2-to-1 transition. Signs your baby is ready include: consistently fighting the second nap for 2 or more weeks, taking a long time to fall asleep at bedtime, or the second nap pushing bedtime too late. Start by gradually pushing the morning nap later by 15-30 minutes every few days until it lands around 12:30-1pm.
If your baby is still on two naps and doing well, that is perfectly fine. Every child is different. However, if you are seeing consistent nap resistance, short second naps, or very late bedtimes, it is likely time to consolidate. The single nap should eventually land between 12:30-2:30pm for most toddlers.
By 18 months, most toddlers have fully transitioned to one nap. This single nap is usually 1.5-3 hours long. If your toddler is still struggling, ensure the nap is well-timed (not too early, not too late) and that bedtime moves earlier if needed. Some toddlers need a 6:30pm bedtime during the transition.
What Should You Do?
When to take action
- Your toddler is cranky in the late afternoon during the transition and needs a slightly earlier bedtime
- Some days your child takes two naps and other days just one during the transition period
- The transition takes 2-4 weeks with some bumpy days
- Your child occasionally falls asleep in the car or stroller in the late afternoon during adjustment
- Bedtime moves temporarily earlier to compensate for lost daytime sleep
- Your child seems chronically overtired for more than a month despite your best efforts to adjust the schedule
- Your toddler stops napping entirely before age 2 and seems exhausted
- Your child is so overtired they are having frequent accidents, falls, or are unable to eat or function normally
- Extreme mood changes or developmental regression that you suspect is related to severe sleep deprivation

Baby Only Napping 30 Minutes
Short naps of 30-45 minutes are extremely common in babies under 6 months. Your baby is waking at the end of a single sleep cycle and has not yet learned to link cycles together during the day. This is developmentally normal and typically improves on its own between 5-7 months as the brain matures.
Baby Fighting Sleep
A baby who fights sleep is usually either overtired, undertired, or going through a developmental leap. It can feel exhausting, but it is very common and does not mean anything is wrong. Adjusting wake windows and creating a calming pre-sleep routine are the most effective strategies.
My Baby Grinds Teeth While Sleeping
Teeth grinding (bruxism) is surprisingly common in babies and toddlers, affecting up to 30% of children. It often begins when babies first get teeth and may continue through early childhood. While the sound can be unsettling, occasional grinding is usually harmless and most children outgrow it by age 6. It may be related to teething discomfort, jaw development, or simply exploring their new teeth.
My Baby Moans in Their Sleep
Moaning, groaning, and grunting during sleep are extremely common in babies and are almost always harmless. Babies spend a large proportion of their sleep in active (REM) sleep, during which they naturally vocalize, twitch, and make facial expressions. These sounds typically decrease as your baby's nervous system matures over the first few months.
My Baby Naps Too Much
How much daytime sleep is "too much" depends heavily on your baby's age. Newborns naturally nap frequently and for long stretches, while older babies and toddlers gradually consolidate daytime sleep into fewer, shorter naps. Excessive daytime napping becomes a concern mainly if it consistently interferes with nighttime sleep or if it signals an underlying issue like illness.
Baby Needs Rocking to Sleep
Rocking your baby to sleep is a perfectly natural and loving way to help them drift off. It is not a bad habit - it is responsive parenting. If rocking is working for your family, there is no need to change anything. If you would like your baby to learn to fall asleep with less help, gentle, gradual approaches work best.
