If you’re wondering how many hours a newborn, 1-month-old, 2-month-old, 3-month-old, 4-month-old, 5-month-old, or 6-month-old should sleep, this page can help you compare your baby’s total daily sleep with age-based ranges and understand when differences may still be normal.
Answer a few questions about your baby’s age and total sleep in a full day to get personalized guidance that fits this stage.
Baby sleep hours per day can vary quite a bit, especially in the newborn months. Some infants sleep in many short stretches, while others begin to consolidate sleep a little earlier. Looking at total sleep across a full 24-hour day is often more helpful than focusing on one nap or one night. In general, younger babies tend to sleep more overall, and total infant sleep hours gradually shift as babies grow, feed more efficiently, and spend longer periods awake.
Parents often ask how many hours should a newborn sleep or how many hours should a 1 month old sleep. At this stage, many babies sleep about 14 to 17 hours in 24 hours, though patterns are usually irregular and broken up by feeding.
If you’re searching how many hours should a 2 month old sleep or how many hours should a 3 month old sleep, many babies are still around 14 to 17 hours total, with some beginning to show slightly longer nighttime stretches.
For parents asking how many hours should a 4 month old sleep, how many hours should a 5 month old sleep, or how many hours should a 6 month old sleep, many babies are closer to about 12 to 16 hours in 24 hours, including naps.
Frequent feeding, cluster feeding, and growth spurts can change how sleep is distributed across the day and night without necessarily changing total sleep dramatically.
As babies become more alert, practice new skills, and spend longer awake, sleep may look less predictable for a while even when total daily sleep remains within a typical range.
Some babies naturally sleep in shorter stretches, while others settle more easily. Daytime stimulation, nap timing, and bedtime routines can also influence total infant sleep hours.
A baby does not need to match an exact number every day to be doing well. It’s common for sleep totals to move up or down from one day to the next. What matters most is the overall pattern: your baby’s age, feeding, alertness during wake windows, and whether sleep seems to be trending far below or above expected ranges over time. If you’re unsure whether your baby’s sleep is typical, a brief assessment can help put the numbers in context.
If your baby’s total sleep in 24 hours is regularly much lower or higher than expected for their age, it may be worth getting more personalized guidance.
Sleep hours are only one piece of the picture. Feeding difficulty, unusual sleepiness, or persistent fussiness can matter too.
Many parents are unsure whether to include contact naps, stroller naps, or short overnight stretches. A structured assessment can help you evaluate the full 24-hour total more clearly.
Many newborns sleep about 14 to 17 hours in a full 24-hour day. Sleep is usually spread across short stretches, and frequent waking for feeds is common.
A 1-month-old often still falls in a similar range to a newborn, commonly around 14 to 17 total hours per day, though individual patterns can vary.
Many 2- and 3-month-old babies still sleep around 14 to 17 hours in 24 hours. Some begin to have slightly longer nighttime stretches, but naps may remain inconsistent.
Many babies from 4 to 6 months sleep about 12 to 16 hours total per day, including naps. Sleep can still vary from one baby to another, especially during developmental changes.
Day-to-day variation is common. It’s usually more helpful to look at patterns over several days rather than one isolated day, especially during growth spurts, routine changes, or developmental leaps.
