The daily routine of a 6-month-old
Six months is the month the day becomes predictable. The naps come back at roughly the same times, the nights have lengthened, and you can finally plan an outing without tossing a coin.
It is also the age where you start to feel that the third nap, the late-afternoon one, does nothing more than carry them to bedtime. It shortens, it gets refused one day in three — that is the start of a transition that will take another two or three months.
The day below shows the three-nap rhythm for as long as it holds. The move to two comes later, and forcing it now mostly produces a baby in sleep debt.
