By then, most babies enjoy about 11 hours of sleep at night, with the odd brief waking, and two daytime naps of about one hour 30 minutes each.

By about 18 months, naps will reduce to one a day.y then, most babies enjoy about 11 hours of sleep at night, with the odd brief waking, and two daytime naps of about one hour 30 minutes each.
