How much daytime sleep is right for my baby?
Remember, you can't force a baby to sleep during the day. You can only offer the nap.
For babies 12 weeks and under, offer naps after wake windows of 60-90 minutes. Normal newborn naps last anywhere from 20 to 120 minutes. Check out Short Naps and Newborns for more on this. If you have the newborn class, Will I Ever Sleep Again?, be sure to watch the bonus video on this topic found between Tips 6 and 7.
For babies 3 to 4 months, exceeding about 4.5 hours of daytime sleep can start to negatively impact night sleep.
For babies 5 to 25 months, check out the recommendations for your baby's age in Nap Schedules: 5 Months to 25 Months.
