How to count sleep time and awake time correctly

Sleep time is the time when your baby is napping or sleeping. When a baby sucks on the breast after sleeping or before going to sleep with closed eyes it’s also counted as bedtime, not awake time.

Awake time is the time when your baby is awake. Breastfeeding with open eyes and putting your baby to sleep before he or she begins to fall asleep are awake times.

Total sleep time (TST) is the sum of all night time sleep(s) and the daily naps of the following day. A night's sleep is counted from the time the baby falls asleep at night until he or she woke up in the morning. It is not divided into different dates: before 00:00 and after 00:00.

The total awake time (TWT) is calculated from the same time interval.

It doesn't have to be always 24 hours.

Today the child may go to sleep at 8:00 PM, tomorrow at 9:00 PM. As a result, the calculation period will be 25 hours.

The main thing in establishing a daily routine is to control the waking hours. The child should be awake for the necessary hours for his/her age and you should try not to overexert himself/herself.

Example:

Night sleep from 1st June to 2nd June: 19:00 - 01:00 (sleep time 6 hours). 02:00 - 07:00 (sleep time 5 hours).
Daily nap: 10:00 - 12:00 (sleep time 2 hours). 15:00 - 16:00 (sleep time 1 hour)
Night sleep 2nd June to 3rd June: 20:00 - 06:00

Total:
Total night sleep: 11 hours
Total daily naps: 3 hours
Total sleep time: 14 hours
Total awake time: 11 hours
