The three-to-two-nap transition is often described by parents as one of the easier nap transitions, because the two-nap schedule that results is typically more predictable and family-friendly than the three-nap schedule with its evening catnap. However, the transition itself takes a few weeks to settle, and both too-early and too-late transitions create problems.

Signs of Readiness (6–9 Months)
Consistently resisting the third nap: the late-afternoon catnap takes 20+ minutes to fall asleep or is refused regularly.
Third nap disrupting bedtime: the catnap that falls around 4–5pm is close enough to bedtime that it reduces sleep pressure and makes the 7pm bedtime difficult.
Wake windows comfortably reaching 2.5–3 hours: the baby can stay awake for these windows without overtiredness signs.
Taking longer, more restorative naps: as nap quality improves, fewer naps cover the total need.
The Two-Nap Schedule
Once the third nap is dropped, the schedule shifts to:
- Morning nap: approximately 9–10:30am
- Afternoon nap: approximately 1–3pm
- Bedtime: approximately 6:30–7:30pm (moved earlier initially to compensate)
The afternoon nap gap from last sleep to bedtime (approximately 3.5–4 hours) is typically well-managed at this age.
Managing the Transition
Expect a tired period: the first 2–3 weeks after dropping the third nap often involve earlier fatigue in the late afternoon. Bringing bedtime forward by 30–60 minutes compensates.
The transition may take 4–8 weeks before the schedule fully stabilises.
Early transition signs can overlap with regressions: the 6–8 month developmental period also coincides with a sleep regression. Ensure the transition is truly indicated rather than being a response to a temporary disruption.
Key Takeaways
The transition from three to two naps typically occurs between 6 and 9 months, when wake windows reach approximately 2.5–3 hours. It is one of the most significant nap transitions and usually requires several weeks for the schedule to fully adjust. The two-nap schedule — morning and afternoon — often becomes the most stable nap pattern of infancy, lasting until the 1-to-2 transition at 12–18 months.
