6-Month-Old Sleep Schedule: The 3-to-2 Nap Turning Point

Six months is a milestone month for sleep. Your baby's days are stretching longer between naps, solids are usually just starting, and many babies begin the move from three naps to two. It's a turning point — and like most turning points, it can be a little bumpy. Here's a realistic picture of a six-month sleep day.

How much sleep a 6-month-old needs

The AASM recommends 12–16 hours per 24 hours, including naps, for infants 4–12 months. (AASM pediatric sleep duration consensus)

Most 6-month-olds get roughly 11–12 hours overnight plus around 3 hours of daytime sleep, though babies vary within the healthy range.

Wake windows and naps

Wake windows lengthen to about 2.5 to 3 hours at six months, often longest before bed. Most babies are still on 3 naps at the start of this month but may begin transitioning toward 2 naps as the day's wake windows grow — particularly when the third catnap starts pushing bedtime too late or getting refused.

Six months is also commonly when solids begin. The AAP recommends introducing complementary foods around six months while continuing breast milk or formula. (HealthyChildren.org – starting solid foods) New foods occasionally cause a brief sleep blip, but they don't replace milk as the main nutrition source yet.

A sample day (3-nap version)

• 7:00 a.m. — Wake and milk feed
• ~9:30 a.m. — Nap 1
• Mid-morning — Milk; a small solids "meal" may start here
• ~12:30–1:00 p.m. — Nap 2
• Afternoon — Milk feed, awake time
• ~4:00 p.m. — Nap 3 (short catnap)
• Evening — Solids dinner (if started), milk, bath, calm routine
• ~7:00–7:30 p.m. — Bedtime
• Overnight — Some babies still feed once or twice; follow your pediatrician

As the day shifts toward 2 naps, the catnap drops and the two remaining naps lengthen, with a longer wake window before bed.

What's normal at six months

• A 3-to-2 nap transition in progress — some days look like 3 naps, some like 2.
• Possible brief disruption from new motor skills (rolling, sitting) and starting solids.
• A consolidating night, with longer stretches for many babies (though night feeds remain normal for some).

Keep safe-sleep basics: place baby on the back to sleep on a firm flat surface with no soft bedding. (AAP Safe Sleep – HealthyChildren.org)

Reading the signs of the nap transition

You don't have to guess at when to nudge toward 2 naps — your baby will show you. The signals to watch for: the third catnap getting harder to achieve or shrinking to almost nothing, the morning nap starting late and running long, or bedtime drifting later because the afternoon catnap pushed everything back. When you see two or three of those consistently for a week or more, gradually stretch the morning wake window and let the third nap fall away on its own. Forcing the change before the signs appear usually creates overtiredness; waiting for them makes the transition far smoother.
