How much sleep does a infant need?
Infants (4–11 months) are generally recommended to get 12–15 hours of sleep per night, per National Sleep Foundation guidelines.
Infants are consolidating sleep into longer nighttime stretches plus daytime naps. Total sleep (including naps) matters more than any single "bedtime" at this age.
Example: waking up at 7:00 AM
8:15 PM
7 cycles · 10h 30m sleep
9:45 PM
6 cycles · 9h 0m sleep
11:15 PM
5 cycles · 7h 30m sleep
12:45 AM
4 cycles · 6h 0m sleep
2:15 AM
3 cycles · 4h 30m sleep
Example: going to bed at 10:30 PM
3:15 AM
3 cycles · 4h 30m sleep
4:45 AM
4 cycles · 6h 0m sleep
6:15 AM
5 cycles · 7h 30m sleep
7:45 AM
