Your child will surely get over this soothing-technique during the night by the time he turned 4 or 5 years old. However, if you are still troubled with your child’s head banging is becoming more and more frequent, then here are some of the things that you can do to help them get over this habit.

Do not nag your child just because you feel frustrated whenever he bangs his head. This would not help at all but may even worsen his habit.

Have a different routine before your child sleeps such as reading stories, singing lullabyes, etc.

Give your child a different comfort-thing like stuff toys or little blankets.

The sleeping routines must be followed strictly and you should imply it consistently during your child’s nap time or sleeping time.
