An 8-month-old typically needs 2 to 3 hours of daytime sleep, spread across two or three naps. Most babies this age are settling into a two-nap schedule, though it’s completely normal to still need a third short nap on some days. Individual naps usually last about 60 minutes each, with a possible shorter catnap of 30 to 45 minutes if your baby still takes three.
How Many Naps and How Long
At 8 months, most babies take two to three naps per day. The first two naps should ideally be at least 60 minutes each, and some babies will sleep closer to 90 minutes or even two hours for that first nap. If your baby still takes a third nap, it’s typically a shorter catnap lasting 30 to 45 minutes, usually in the late afternoon.
Total daytime sleep adds up to roughly 2 to 3 hours. Combined with 11 to 12 hours of nighttime sleep, that puts your baby in the recommended range of 12 to 16 hours of total sleep per 24-hour period. If naps consistently run much shorter than 45 minutes, the timing might be off, or your baby could be ready for a schedule adjustment.
Wake Windows Between Naps
The spacing between naps matters just as much as the naps themselves. At 8 months, most babies can handle 2.5 to 3.5 hours of awake time between sleep periods. A baby who just turned 8 months will likely fall on the shorter end of that range, while one approaching 9 months can often stay up longer.
Wake windows also tend to get longer as the day goes on. Your baby might need a nap after just 2.5 hours in the morning but handle 3 to 3.5 hours of awake time before bed in the evening. This is normal and worth paying attention to, because forcing the same gap between every nap can lead to a baby who’s undertired for the morning nap and overtired by bedtime.
A Typical Two-Nap Day
If your baby wakes around 7 a.m., a two-nap day might look something like this: a morning nap around 9:30 or 10 a.m. lasting 1 to 2 hours, followed by an afternoon nap around 2 or 2:30 p.m. lasting 1 to 1.5 hours. Bedtime would fall somewhere between 6:30 and 7:30 p.m., depending on when the last nap ended.
On a three-nap day, both the morning and afternoon naps may be slightly shorter, with a brief catnap squeezed in around 4 or 4:30 p.m. to bridge the gap to bedtime. Having a mix of two-nap and three-nap days is common during this transition period.
Signs Your Baby Is Dropping the Third Nap
Most babies transition from three naps to two somewhere between 7 and 9 months, so your 8-month-old may be right in the middle of this shift. The signs are fairly consistent: your baby starts resisting that third nap, takes longer to fall asleep for it, or skips it entirely without falling apart before bedtime. You might also notice shorter naps across the board, early morning waking, or long stretches of wakefulness in the middle of the night.
One useful signal is nighttime sleep. If your baby is regularly getting less than 10 hours at night while still on a three-nap schedule, dropping to two naps often helps consolidate and lengthen overnight sleep. The transition doesn’t happen overnight. Expect a week or two of mixed days where some days work fine with two naps and others clearly need a third.
Tired Signs to Watch For
Timing naps by the clock is a helpful starting point, but your baby’s behavior is the most reliable guide. Common signs of tiredness at this age include clinginess, fussiness with food, crying or grizzling, demanding more attention than usual, and losing interest in toys. Some babies also pull at their ears, yawn, or stare into space. If your baby had a feed within the last couple of hours and is cranky, tiredness is a likely culprit.
Getting ahead of these cues is important. Once a baby becomes overtired, settling to sleep gets harder, not easier. Overtired babies often fight naps, take longer to fall asleep, and then sleep for shorter stretches, which creates a frustrating cycle. If you’re consistently seeing meltdowns at nap time, try offering sleep 15 to 20 minutes earlier.
Why Naps May Suddenly Get Worse
Around 8 months, many babies go through a sleep regression tied to developmental milestones. Crawling, pulling up to stand, and sitting up independently all tend to emerge around this age, and these new physical skills can make your baby restless in the crib. Teething is also common and can add discomfort at nap time.
During a sleep regression, you might see difficulty falling asleep, more fussiness around nap time, or a shift where naps get longer but nighttime sleep suffers. This is temporary. It typically lasts two to four weeks and resolves as your baby adjusts to their new abilities. Keeping nap timing consistent during this period helps your baby return to a predictable schedule once the regression passes.
When Naps Are Consistently Too Short
If your baby regularly wakes after 20 to 30 minutes and seems cranky afterward, the nap isn’t restorative enough. Short naps at this age usually come down to one of a few things: wake windows that are too short (the baby wasn’t tired enough), wake windows that are too long (the baby was overtired and couldn’t settle deeply), or a sleep environment that’s too stimulating.
Try adjusting wake windows by 15 minutes in either direction and sticking with the new timing for three to five days before deciding whether it helped. Small shifts can make a surprisingly big difference. Some babies also nap better in a darker, quieter room, especially as they become more aware of their surroundings around this age.
