Below is an example of what you do when your baby falls asleep.  You press the green button, and when they wake you will press the same button.  NOTE: Only record wake ups that are 15 minutes or longer

If you forget to track your baby's sleep you can go back in the app and record it. For example this shows me going back in my son's data to track the previous night's onset of sleep until when he woke in the morning.
