Sleep from age 1 to 3: what to expect
Between the move to one nap, separation anxiety, and the first bedtime protests, this stage reshapes the whole family's sleep.
Between 1 and 3 years old, total sleep needs are generally around 11 to 14 hours per 24-hour period, naps included. Most children move from two naps to a single afternoon nap somewhere between 12 and 18 months, a transition that can come with a few rougher weeks.
This is also the stage when separation anxiety often peaks, which can make bedtime harder even for a child who used to sleep well: crying when a parent leaves the room, night wakings that need extra comfort, resistance to being alone. A stable, predictable bedtime routine helps get through this phase.

Around 18 months to 2 years, many children start the transition from crib to a bigger bed, often driven by motor development (the ability to climb over the crib rail) rather than a fixed age. This transition can temporarily disrupt sleep as the young child tests the limits of their newfound freedom of movement.
As language and imagination develop rapidly, some children this age also start expressing fears (the dark, being alone) or having occasional nightmares. Naming those fears without minimizing them, while keeping clear and gentle limits at bedtime, helps the child feel secure.
