Question: my 23 month old is sleeping a lot?
Answer: 23-Month-Old Sleep Most 23-month-olds need around 11 to 12 hours of nighttime sleep, plus a nap of about 1.5 to 3 hours, for a total of about 13 to 14 hours of sleep per day. Is your 23-month-old waking up at night? Sleep regression can happen because of teething, separation anxiety or a change in sleep routine.
