A 6-month-old needs 12 to 16 hours of total sleep per day, split between nighttime sleep and daytime naps. Most babies this age get about 10 to 12 hours at night and another 2.5 to 3.5 hours during the day across multiple naps.
How Daytime Naps Break Down
At 6 months, most babies take three naps a day. The first two naps are the longer ones, ideally lasting 60 to 90 minutes each. The third nap is a shorter “catnap” of about 30 to 45 minutes, usually in the late afternoon. That third nap helps bridge the gap to bedtime without pushing it too late.
Total daytime sleep should land somewhere around 2.5 to 3.5 hours. If your baby is consistently napping much more than that, nighttime sleep may suffer. On the flip side, a baby who skips naps or sleeps very little during the day often has a harder time settling at night because overtiredness makes it paradoxically harder to fall asleep.
Wake Windows Between Naps
The stretches of awake time between sleep periods matter just as much as the sleep itself. At 6 months, most babies do well with wake windows of about 2 to 2.5 hours. That means from the moment your baby wakes up from one nap, you’re watching for sleepy cues roughly two hours later. Signs like eye rubbing, yawning, or fussiness usually mean the window is closing. Pushing too far past it can lead to a baby who’s wired and fights sleep.
Nighttime Sleep and Night Feedings
By 6 months, many babies are capable of sleeping long stretches at night without eating. UCSF Benioff Children’s Hospitals notes that most 6-month-olds do not need nighttime calories to grow properly. Babies who still wake to eat at this age are often doing so out of habit rather than hunger. That said, every baby is different, and some may still benefit from one feeding overnight, particularly if they’re on the smaller side or haven’t fully ramped up daytime intake with solids.
If your baby has been sleeping through the night and suddenly starts waking again, a sleep regression is the more likely culprit than hunger. More on that below.
The 6-Month Sleep Regression
Right around 6 months, many parents notice their baby’s sleep falls apart after weeks or months of improvement. This is driven by a wave of developmental changes happening all at once. Your baby may be learning to sit up, starting to crawl, beginning to teethe, and developing object permanence, which is the understanding that you still exist when you leave the room. Any of these milestones can disrupt sleep.
The regression typically shows up as more frequent night waking, difficulty settling at bedtime, or a baby who suddenly wants more attention and resists being left alone in the crib. It’s temporary, though there’s no precise timeline for how long it lasts. Most parents report it resolving within a few weeks as the baby adjusts to new skills. Keeping your routine consistent through this period helps your baby return to their normal pattern faster.
How Starting Solids Affects Sleep
Six months is when most families begin introducing solid foods, and this can have a real effect on sleep. A large study from King’s College London found that babies who started solids slept about 16 minutes longer per night and woke less frequently compared to babies who were exclusively breastfed. That’s nearly two extra hours of sleep per week. The differences peaked right around 6 months. While 16 minutes may sound small, parents in the study reported fewer sleep problems overall, and their own quality of life improved in tandem.
This doesn’t mean loading up on solids before bed will knock your baby out, but it does suggest that adequate daytime nutrition, including both milk and solid foods, supports better nighttime sleep at this age.
Safe Sleep at 6 Months
The basics of safe sleep still apply at this age. Your baby should sleep on their back, on a firm, flat mattress with a fitted sheet, in their own crib, bassinet, or portable play yard. Keep the sleep space clear of blankets, pillows, stuffed animals, and bumper pads. Avoid letting your baby sleep in a swing, car seat (unless you’re actually driving), or on a couch or armchair.
One common question at 6 months is what to do when your baby rolls onto their stomach during the night. If your baby can roll both ways on their own, you don’t need to keep flipping them back. Just continue placing them on their back at the start of every sleep period and let them find their preferred position from there.
