Girls, can you please tell me how to normalize sleep for my son who takes a long time to fall asleep at night. We leave around 1-2 hours after he falls asleep. How do we normalize his sleep? He's awake for a maximum of two hours during the day and then sleeps for an hour, and so on. I put him to bed at 11 pm, but he wakes up after half an hour. Now we don't sleep until 2 am.
