Skipping a third nap once does not establish a permanent transition. Look at whether the pattern changes across several days and how your baby manages. Age alone cannot give you a required switch date.

One day or a new pattern?
A day with appointments, travel or an unusually long nap may not be representative. Note what was different before making a new plan. Ask not only “How many naps?” but “What shaped this day?”.
Consider total sleep and wellbeing
Nap count does not describe total nap time. Three short naps can add up to less or more sleep than two longer ones. Include the night and how your baby seems after waking. A lower nap count is not a badge of progress.

Transition days can vary
If you change how you support sleep, watch the response. Do not keep a clearly tired baby awake just because today is supposed to follow a two-nap plan. Adapt to the need you observe.
The illustration deliberately shows three different days. There is no point where the old nap count becomes forbidden. The examples are for comparison only.

Keep observation manageable
For a few days, choose one question, such as whether the final nap often drops out and what happens that evening. A brief note on timing and wellbeing is enough. Missing entries remain unknown; they do not count as zero minutes.
If a change creates more strain, you do not need to push through. Discuss ongoing difficulties with a professional rather than trying ever-longer stretches awake.

When to seek support
Seek medical help if your baby seems unwell, feeds poorly or is unusually difficult to wake. Ongoing parental exhaustion also deserves support. For breathing difficulty or unresponsiveness, call your local emergency number.
Common questions
Does one refused nap prove the transition?
No. Consider several days and their context.
Should I record an unknown nap as zero?
Only if you know no sleep happened. An observation gap remains a gap.
