How Many Hours Should an 11-Month-Old Baby Sleep?

Few things are more satisfying to tired parents than the sight of their baby sleeping soundly.

11 to 14 hours

According to Baby Center, a 9 to 12 month old baby should sleep between 11 and 14 hours at night, though not necessarily continuously, and have two daytime naps that last one or two hours. At this age, some babies can sleep for nine or 10 hours straight without waking. Other babies still wake once or more during the night.

Developmental Milestones May Affect Sleep

Sleep may be interrupted by hitting a developmental milestone such as walking or crawling, or by separation anxiety, which is common in babies this age. Sleep may also be temporarily interrupted by teething or illness.

Bottom Line

Some children may sleep two full hours more or less than the recommended amount and still be well-rested and healthy. As long as the daytime routines of you and your child are not impaired by lack of rest, you are both getting enough sleep.
