The daily routine of a 7-month-old
Seven months is often a comfortable month: two solid naps, a shorter third, nights that hold. The rhythm is stable enough to plan a day ahead.
It is also the month the late-afternoon nap starts causing trouble. It gets refused, it shortens, or it ends too late and pushes bedtime. All three lead to the same place: the transition to two naps is coming.
It is not here yet. As long as your baby accepts the third nap more than one day in two, it still has its place in the day.
