Hello, Night terrors are frightening for a parent to witness. The child appears agitated and panicked and confused and dazed and may have his eyes open. At the beginning of the night terror, he can cry or scream. He may mumble, is often clumsy, and push a parent away. The child is unaware of what he is doing and has no memory of these events when he wakes up. He might become more upset if you attempt to calm him down. He may seem to be awake but is actually asleep. A night terror occurs within 1-2 hours after falling asleep. Duration: a few minutes to an hour. Night terrors often run in families. Can occur during naps, as well. Usually, require no treatment; however, if there is injury, violence, or serious disruption to family, then speak to his doctor. Another possibility to consider is night walking in which the child learns to need something(being rocked, fed, blanket) in order to fall asleep at bedtime. This same need can be present in order to fall back to sleep when waking during the night. When the children needs are not readily available during the night(being held, having a parent present) prolonged night walking scan occur. Here are a few tips to reduce night walking:- Make to be Chat Doctor. - Put your son to bed
