A 5-month-old typically sleeps 11 to 12 hours at night, though most won’t do that in one unbroken stretch. Total sleep over 24 hours for babies aged 4 to 12 months falls between 12 and 16 hours, with nighttime making up the bulk of that and daytime naps filling in the rest.
What Nighttime Sleep Looks Like at 5 Months
Most 5-month-olds are capable of sleeping 6 to 8 hours without waking, a milestone that generally emerges around 3 months of age. But “sleeping through the night” at this age rarely means a full 12 hours without a peep. Your baby will likely still wake once or twice, especially if breastfed, and that’s normal. The longest unbroken stretch tends to happen in the first half of the night, with lighter, more wakeful sleep toward the early morning hours.
A realistic picture: bedtime around 7:00 or 7:30 p.m., one or two brief wake-ups, and a morning wake time around 6:00 to 7:00 a.m. Some babies this age surprise their parents by sleeping 10 or 11 hours straight. Others still wake every 3 to 4 hours. Both can be perfectly healthy.
Night Feedings at 5 Months
Whether your baby still needs to eat overnight depends partly on how they’re fed. Formula-fed babies can often go longer between feedings because formula digests more slowly than breast milk. For formula-fed babies, night feeds can reasonably be phased out starting around 6 months. For breastfed babies, night weaning is generally appropriate closer to 12 months, though many breastfed babies naturally reduce night feeds well before that.
There’s no rush to eliminate night feeds at 5 months. Waking to eat at this age is common, and many babies still need one or two overnight feeds for both nutrition and comfort. As your baby gets older, these wake-ups tend to decrease on their own.
How Daytime Naps Affect Night Sleep
It might seem logical that keeping your baby awake longer during the day would help them sleep better at night. The opposite is true. An overtired baby actually has more trouble falling and staying asleep overnight. Napping during the day builds the foundation for solid nighttime sleep.
At 5 months, most babies need 3 to 4 naps per day, totaling about 2.5 to 3.5 hours of daytime sleep. That typically breaks down into a morning nap, an afternoon nap, and one or two shorter naps in the late afternoon or early evening. If your baby is a long napper, capping individual naps at 1.5 to 2 hours helps preserve enough sleep drive for nighttime. When a single nap runs too long, it can steal from overnight sleep or make later naps harder to achieve.
Signs Your Baby Is Ready for Sleep Training
Five months falls squarely in the window when sleep training becomes an option. Babies are generally ready around 4 months, when their sleep cycles start maturing and their internal body clock begins regulating day and night more clearly. At this age, many babies can learn to fall asleep independently and no longer require overnight feeds from a developmental standpoint (though some still benefit from them).
Sleep training doesn’t mean one single approach. Several methods exist, and they vary mainly in how much direct comfort you provide:
- Graduated check-ins: You place your baby in the crib drowsy but awake, leave the room, and return at timed intervals to briefly reassure them without picking them up. The intervals get longer each night.
- The chair method: You sit in a chair beside the crib until your baby falls asleep, then move the chair farther away every few nights until you’re out of the room entirely.
- Pick up, put down: When your baby fusses, you pick them up and soothe them, then place them back in the crib once they’ve settled. You repeat as needed.
- Full extinction: After a safe bedtime routine, you say goodnight and don’t return until morning or the next scheduled feed. This tends to work fastest but involves more crying upfront.
- Bedtime fading: You shift your baby’s bedtime earlier by about 15 minutes each night until you reach the time you’re aiming for.
No single method is best for every family. The key principle across all of them is putting your baby down drowsy but awake, so they learn to bridge sleep cycles without needing you to recreate the exact conditions that got them to sleep in the first place.
Sleep Safety at 5 Months
Five months is right around the age when many babies learn to roll, and that changes a few things about their sleep setup. If your baby is showing any signs of rolling, swaddling should stop immediately. A swaddled baby who rolls onto their stomach faces a higher suffocation risk because they can’t use their arms to reposition.
Once your baby can roll comfortably in both directions (back to stomach and stomach to back), you don’t need to keep flipping them onto their back every time they turn over. Always place them on their back to start, but let them find their own position from there. The crib should be completely clear of blankets, pillows, stuffed animals, and bumper pads. A firm mattress with a fitted sheet is all that belongs in there.
Building a Consistent Bedtime
Your baby’s own cues are the most reliable guide to the right bedtime. Rubbing eyes, fussing, looking away from stimulation, and yawning are all signals that the window for easy sleep is open. Missing that window tends to lead to overtiredness, which makes falling asleep harder, not easier.
Keeping bedtime and wake time roughly consistent from day to day helps your baby’s internal clock settle into a rhythm. A short, predictable routine before bed, something like a feed, a diaper change, a song, and lights out, signals to your baby that sleep is coming. The routine itself matters less than the consistency of it.
