A five-month-old needs roughly 12 to 16 hours of total sleep per day, split between nighttime sleep and daytime naps. Most of that sleep happens at night, with about 3 to 3.5 hours spread across daytime naps. Getting the balance right between night sleep and naps makes a noticeable difference in your baby’s mood, feeding, and development.
Total Sleep Breakdown: Night and Day
At five months, your baby is likely sleeping 10 to 12 hours overnight, though not necessarily in one unbroken stretch. Most babies this age still wake for feedings. Breastfed infants typically need one to three feedings per night, while formula-fed babies usually need one to two. These wake-ups are normal and don’t mean your baby has a sleep problem.
During the day, aim for about 3.5 hours of total nap time spread across three naps. Some days all three naps will run about an hour to an hour and a half each. Other days, the first two naps are longer and the third is a short catnap of 20 to 30 minutes, just enough to bridge the gap to bedtime. Both patterns are fine as long as total daytime sleep lands in that 3 to 4 hour range.
Wake Windows Between Naps
Five-month-olds can handle about 2 to 2.5 hours of awake time between sleep periods, sometimes stretching to 3 hours later in the day. These stretches include feeding time and play, not just independent activity. Keeping wake windows in this range helps prevent overtiredness, which, counterintuitively, makes it harder for babies to fall asleep and stay asleep.
The first wake window of the day is often the shortest. If your baby wakes at 7 a.m., the first nap might start around 9 or 9:15. Later wake windows can be slightly longer, with the stretch before bedtime being the longest at closer to 2.5 hours.
How to Spot Tired Cues
Your baby will show you when sleep is coming before a schedule tells you. Early tired cues include yawning, becoming quiet and losing interest in play, jerky arm or leg movements, and rubbing their eyes. Some babies make a distinctive sleepy sound or pull faces. These are your green light to start winding down.
If you miss those early signals, overtiredness sets in quickly. An overtired five-month-old looks hyperactive rather than drowsy: glazed eyes, frantic movements, and crying that escalates fast. Putting a baby down at the first signs of tiredness is far easier than trying to settle an overtired one.
A Typical Day at Five Months
Schedules at this age are loose, built around your baby’s cues rather than strict clock times. But a representative day gives you a frame to work with:
- 6:30–7:00 a.m. Wake and feed
- 9:00–10:15 a.m. Nap 1 (about 1 to 1.5 hours)
- 10:15 a.m. Feed and play
- 12:30–2:00 p.m. Nap 2 (about 1 to 1.5 hours)
- 2:00 p.m. Feed and play
- 4:00–4:30 p.m. Nap 3 (a shorter catnap, 20 to 45 minutes)
- 5:00 p.m. Feed and play
- 6:30–7:00 p.m. Bath, quiet time, feed
- 7:00–7:30 p.m. Bedtime
This is a starting point, not a prescription. Some babies run 30 minutes earlier or later across the board. The consistent elements matter more than the exact times: three naps, 2 to 2.5 hour wake windows, and a bedtime that falls roughly 12 hours before your desired morning wake time.
Why Sleep May Be Bumpy Right Now
Five months sits in a window of rapid developmental change. Your baby may be learning to roll, starting to babble more, or becoming much more aware of their surroundings. All of these milestones can temporarily disrupt sleep. A baby who was sleeping longer stretches might suddenly wake more often, or naps that were predictable may shorten for a week or two.
This is not a step backward. The disruption is a sign that your baby’s brain is busy consolidating new skills. Sleep typically settles back down within a couple of weeks once the milestone is established. In the meantime, keeping wake windows consistent and responding to tired cues gives your baby the best chance of getting enough rest even during a rough patch.
Safe Sleep Setup
At five months, your baby should still sleep on a firm, flat mattress in a safety-approved crib or bassinet. No blankets, pillows, bumper pads, or stuffed animals in the sleep space. The CDC recommends keeping your baby’s crib in your room for at least the first six months.
If your baby has started rolling, you don’t need to reposition them every time they flip onto their stomach, but always place them on their back to start each sleep. A sleep sack is a safe alternative to loose blankets for keeping your baby warm.
