The daily routine of a 10-month-old
Ten months is the month of false signals. Your baby refuses the morning nap three days running, you conclude they are moving to one nap, and the following week is a disaster.
The move to a single nap happens between fourteen and eighteen months. At ten months a nap refusal almost always comes from something else: a morning awake window that has become too short, a motor skill in progress, or simply a bad day.
The right answer at ten months is to lengthen the first awake window by fifteen to thirty minutes, not to drop a nap.
