Quick Answer
Wake windows for a 6 month old are typically 2 to 2.5 hours. Most 6 month olds are on 3 naps or transitioning to 2, with wake windows lengthening noticeably from the 5-month stage. Six months is also when solid foods typically begin — which can affect sleep temporarily as the digestive system adjusts.
What are wake windows at 6 months?
At 6 months, wake windows are in the 2 to 2.5 hour range for most babies. The 3-to-2 nap transition typically begins between 6 and 8 months — so some 6 month olds are still on 3 naps while others are beginning to show readiness for 2.
Six months is also a significant developmental period — sitting independently, beginning solid foods, and increased social awareness all affect sleep patterns.
Wake window ranges at 6 months
First wake window: 2 to 2.25 hours
Middle window: 2 to 2.5 hours
Final window before bed: 2.25 to 2.5 hours
Sample schedule for a 6 month old (2 naps)
7:00am — Wake and feed. 9:00–9:15am — Nap 1 (1 to 1.5 hours). 10:30am — Wake from nap 1. 1:00–1:15pm — Nap 2 (1 to 1.5 hours). 2:30–3:00pm — Wake from nap 2. 7:00–7:30pm — Bedtime.
The 3-to-2 nap transition at 6 months
Signs of readiness for 2 naps: consistently refusing or barely taking the third nap, managing well on 2-nap days without obvious overtiredness, bedtime being pushed past 8pm because of the third nap.
Signs they still need 3 naps: becoming overtired without the third nap, night sleep significantly worse on 2-nap days.
Solid foods and sleep at 6 months
Starting solid foods at 6 months can temporarily affect sleep — sometimes positively (fuller baby), sometimes negatively (digestive adjustment). The effect is usually short-term, lasting 1 to 2 weeks. Do not make major schedule changes in response to sleep disruption during the first few weeks of solids introduction.

If you're not sure what schedule your baby actually needs right now, this is exactly what I look at with families. A personalised plan makes more difference than any generic schedule.
Frequently Asked Questions

When should a 6 month old go to bed?
Bedtime between 6:30 and 7:30pm works for most 6 month olds. Earlier within that range is appropriate if naps have been short.
