Later infancy (8 to 12 months): separation anxiety and mobility can affect sleep

In the second half of the first year, many infants begin to sleep more consolidated night stretches, often totaling around 11 to 14 hours in 24 hours. However, mobility milestones like crawling and standing, plus the development of separation anxiety, can increase nighttime awakenings. Some babies will begin to transition to two naps and then to one nap toward the end of this period.

Toddlers and transitions (12 to 24 months): nap consolidation and new challenges

As children move into the toddler years, total sleep needs remain high though daytime sleep consolidates. For children 12 to 24 months, typical sleep is about 11 to 14 hours in 24 hours. Many toddlers transition from two naps to one nap sometime between 15 and 18 months. Disruptions such as illness, travel, daycare changes, and emerging independence or bedtime resistance can reduce sleep temporarily.

When less sleep is a concern and how to seek help

Occasional short stretches of sleep are normal, especially around developmental milestones, illness, or travel. However, persistent sleep that is far below age-appropriate ranges while also affecting growth, feeding, mood, daytime alertness, or causing extreme parental distress is a reason to seek professional help. Red flags include poor weight gain, very low daytime alertness, breathing pauses or noisy breathing, and severe difficulty settling even with consistent, gentle strategies.

A gentle guide to baby development support: Is Your Baby Sleeping TOO Little? Age-by-Age Guide to Restful Nights

Is Your Baby Sleeping TOO Little? Age-by-Age Guide to Restful Nights It is normal to worry when your baby seems to sleep less than you expected. Sleep needs change quickly in the first years, and knowing typical ranges plus gentle, attachment-safe strategies can help you support better rest for your child and peace of mind for you. Newborns (0 to 2 months): short, frequent sleep and feeding-driven nights In the first weeks, most newborns sleep in short bursts around the clock. Typical total sleep for this age is about 14 to 17 hours in 24 hours, but much of that is broken into naps lasting 30 minutes to 2 hours. Nighttime sleep is not yet consolidated because small stomachs require frequent feeding and the circadian rhythm is still maturing. If your newborn seems to be sleeping far less than these averages, check feeding patterns and growth. Frequent waking for feeding and comfort is expected and important for healthy weight gain and bonding. Gentle measures that support better sleep include swaddling safely while the baby cannot yet roll, offering cue-based feeding, using consistent calming cues such as soft sound or dim lighting at night, and practicing responsive soothing that helps the baby learn to settle with help. Early infancy (3 to 4 months): more organized sleep and emerging patterns By around 3 to 4 months, many babies begin to show longer stretches at night and longer daytime naps as the circadian rhythm strengthens. Average total sleep for this period tends to be around 12 to 16 hours in 24 hours, with nighttime stretches sometimes reaching 4 to 6 hours. However, developmental leaps, growth spurts, and teething can temporarily reduce sleep. If your baby is sleeping less than expected, focus on consistent daytime cues and a calming bedtime routine. Start to cluster wakeful periods into more predictable wake windows of roughly 60 to 120 minutes depending on the baby, and look for sleepy signals such as rubbing eyes, yawning, or losing interest in play. Gentle settling strategies that preserve attachment include picking up to soothe, shush-patting, feeding if hungry, and gradual shortening of sleep-onset assistance over several nights while remaining responsive to distress. Mid infancy (5 to 7 months): consolidating night sleep and nap transitions Between about 5 and 7 months many babies will consolidate sleep further, often showing a longer nighttime stretch and fewer daytime naps. Typical sleep for this age is around 11 to 15 hours in 24 hours, with many babies taking two to three naps and sleeping a longer block at night. Some babies begin to sleep six to nine hours at a time, but others still wake for feeds, comfort, or because of developmental milestones. If your baby is sleeping less than the usual range, check nap timing and the overall sleep pressure. Late or short naps can make nights harder, and too much awake time can cause overtiredness, which paradoxically makes settling and staying asleep more difficult. Gentle steps that
