A few little questions.
Should I drop a nap on a certain birthday?
The cited span is typical, not a deadline. A consistent pattern and the child’s ability to handle longer awake time matter.
Can some days still need the old nap count?
Mixed days can occur during a transition. Protect rest opportunities and follow cues.
What if the last nap is missed?
The day may need an earlier bedtime. A sample cannot predict the effect for every child.
Does dropping a nap mean dropping a night feed?
Those are separate decisions. Discuss night feeding and growth with the pediatrician.
