Most 13-month-old infants sleep 11 to 12 hours a day, including naps, so your daughter is only an hour short of the average. If she seems well-rested the next day, this may be enough sleep. But if she seems tired or irritable, or nods off to sleep frequently during the day, these are signs that she needs more sleep. Below is a chart of average sleeping times for children of different ages.
|Age||Hours per Day|
|Birth to 3 months||14 to 18|
|3 to 6 months||14 to 16|
|6 months to 2 years||12 to 14|
|2 to 5 years||10 to 12|
An 11 p.m. bedtime is unusually late for a 13-month-old. Modern lifestyles often push bedtimes later, especially among working couples who might not get home until six or seven in the evening and prefer that their baby take a late afternoon nap and be well-rested for quality time in the evening. Other parents prefer a later bedtime for their baby so they can get that extra hour of sleep in the morning. Still other parents want an earlier bedtime so they can get in some baby-free couple time in the evening.
Use the bedtime that works for you and your baby. If an 11 p.m. lights-out keeps your baby rested and suits your schedule, stay with it.
