A 6-month-old needs about 12 to 15 hours of total sleep per day, including nighttime sleep and naps. That’s the range recommended by the National Sleep Foundation’s expert panel for infants aged 4 to 11 months. Most of that sleep happens at night, with the rest spread across two or three daytime naps.
Nighttime and Daytime Sleep Breakdown
At 6 months, your baby typically sleeps 10 to 11 hours at night and takes about 3 naps during the day, each lasting 1 to 2 hours. The third nap of the day is often shorter, sometimes just 30 to 45 minutes. That adds up to roughly 13 to 14 hours of total sleep, right in the middle of the recommended range.
Some babies fall slightly outside that window. The National Sleep Foundation considers 10 to 11 total hours “may be appropriate” for some infants, and the same goes for up to 16 to 18 hours. Consistently sleeping fewer than 10 hours or more than 18 hours in a 24-hour period falls outside what’s considered healthy.
Wake Windows Between Naps
At this age, most babies can handle 2 to 3 hours of awake time between sleep periods. These wake windows tend to get longer as the day goes on. Your baby might only need about 2 hours of awake time before their first morning nap but can stay up closer to 3 hours before bedtime. Paying attention to these windows matters because pushing past them leads to overtiredness, which paradoxically makes it harder for babies to fall asleep and stay asleep.
Night Feedings at 6 Months
A common question parents have alongside sleep duration is whether their baby still needs to eat overnight. By 6 months, most healthy babies don’t need nighttime feedings for nutrition. UCSF Benioff Children’s Hospitals notes that while many babies still wake to eat at this age, they’re doing so out of habit rather than caloric need. That said, every baby is different, and some may still benefit from a feeding, particularly if they were born early or are on the smaller side. The key point is that a 6-month-old’s body is generally capable of going through the night without food.
Why Sleep Often Falls Apart at 6 Months
If your baby was sleeping well and suddenly isn’t, you’re likely dealing with a sleep regression. Six months is a big developmental moment. Your baby is learning to sit up, possibly starting to crawl, and teething often kicks in around this time. All of that physical and cognitive growth can temporarily disrupt sleep patterns.
There’s also an important mental shift happening between 6 and 9 months: your baby begins to understand object permanence. They now realize that when you leave the room, you still exist somewhere. That awareness can make them resist being put down or left alone at bedtime, because they know you’re out there and they want you back. Combined with teething discomfort and the excitement of new motor skills, this period can feel like a perfect storm for disrupted nights.
Sleep regressions at this age typically last a few weeks. They’re not a sign that anything is wrong. They’re a byproduct of your baby’s brain and body developing rapidly.
Building a Schedule That Works
A realistic 6-month-old schedule revolves around three naps and a consistent bedtime. A sample day might look something like this: wake up around 7 a.m., first nap around 9 a.m., second nap early afternoon, a short third nap in the late afternoon, and bedtime between 7 and 8 p.m. The exact times matter less than keeping wake windows in that 2 to 3 hour range and watching your baby’s sleepy cues (rubbing eyes, yawning, fussiness).
Many babies transition from three naps to two somewhere between 6 and 8 months. You’ll notice this happening when the third nap becomes a battle or starts pushing bedtime too late. When that shift happens naturally, the remaining two naps usually get a bit longer to compensate.
Safe Sleep Setup
At 6 months, the basics of safe sleep still apply. Place your baby on their back for every sleep, whether it’s a nap or nighttime. Use a firm, flat mattress in a safety-approved crib with only a fitted sheet. Keep blankets, pillows, bumper pads, and stuffed animals out of the sleep area. If your baby rolls onto their stomach on their own (which is common at this age), you don’t need to reposition them, but always start them on their back.
Room sharing, where your baby sleeps in your room but on their own surface, is recommended for at least the first 6 months. Watch for signs of overheating like sweating or a hot chest, and dress your baby in a sleep sack rather than loose blankets to keep them warm safely.
