| Age | Total Sleep | Avg. Wake Time* | Bedtime | Notes |
|---|---|---|---|---|
| Newborn | 15-18 hours | Varies | N/A | Newborns need to eat frequently and will wake round the clock to feed, so a fixed bedtime is obsolete at this age. Watch your baby’s sleep cues closely, and put down for sleep at the first signs of tiredness. |
| 1-4 Months | 14-15 hours | Varies for 1-2 month olds; 3-4 month olds average 1-2 hours between naps | 8-11 p.m. | User the later bedtime for younger babies. By 3 or 4 months, you can gradually shift to using the earlier bedtime, as your baby (hopefully!) starts to sleep for one longer stretch at night. |
| 4-8 Months | 14-15 hours | Average wake time is 2-3 hours | 6-7:30 p.m. | Most babies are ready for a predictable schedule by about 6 months. Regular naps emerge at this time (4 naps at first, and then gradually moves to 3 naps). Use the earlier bedtime during the transition from 4 naps to 3, to ward off over tiredness. |
| 8-10 Months | 12-15 hours | Average awake time is about 3 hours | 6-7 p.m. | Most babies are taking 2 naps at this age. This is also prime time for the 8/9/10 month sleep regression! Use the earlier betimes if the regression has your baby napping less or waking more at night, and becoming overtired. |
| 10-15 Months | 12-14 hours | Average awake time is 3-4 hours | 6-8 p.m. | Stick with 2 naps, if possible; most babies aren’t ready to transition to one nap until 15-18 months. If your baby goes through the 12 month nap regression, use the earlier bedtime to make up for lost nap sleep. |
| 15 Months-3 Years | 12-14 hours | Average awake time is about 5 hours | 6-8 p.m. | Your toddler will transition to needing just one afternoon nap by about 18 months. That nap should be about 2-2.5 hours in length. Use the earlier bedtime during the transition from 2 naps to 1, and during the 18 month and 2 year sleep regressions, to make up for any lost sleep. By 2 years of age, you should start using 7:00 as your earliest bedtime; the 6:00 bedtime is more appropriate for younger toddlers. |
| 3-5 Years | 11-13 hours | Average awake time is about 12 hours, if toddler/preschooler is no longer napping | 7-8:30 p.m. | Most children give up the afternoon nap at this stage. Substitute an afternoon rest time in for the nap time. Try to time bedtime so that you allow for roughly 12 hours of night sleep, for children who are no longer napping. Use the later bedtime for children who are still transitioning away from the afternoon nap. |
