Girls, the baby cries in the evening and can't fall asleep. Wants to, but can't. Wakes up at 5 and then only at night. It seems hard to stay awake for 4 hours, it gets restless. It is probably nervous and crying because of this. This happens from 6 to 9 pm until it falls asleep at night. Sometimes it may fall asleep, but it will sleep for 10 minutes with superficial sleep and wakes up. What is the reason for such behavior? Share your experience and opinion. Please.
