The child, 3 years old, gets irritated and starts hitting his head on the floor. Why? Use child psychology?

Don`t give a sh.it to the child. He will learn that he is not more important than other people.

My son did that at three and lasted till almost five. He is also very hyper active, sensitive, impulsive, and loud. Also, I really do not agree with everyone else saying that it is for attention. I do not think my son was trying to get attention but instead it was his way of releasing stress. My son would hit his head into any hard surface when the stress hit. One time he was four years old and he did it into a brick wall.

Its manipulation (by him) and an attention getter. He knows you'll come a running every time he does this, so when he wants his way, Bang! with the head, and guess what? You drop what your doing and come a running. Ignore him next time, turn your back on him and talk on the phone. He'll immediately stop, run over until he's within sight, and start it again. Ignore him enough and he'll finally get the idea that this trick isn't working anymore.

This is just the child manipulating you. He hurts himself on purpose and you give him what he wants as a result.

Just let him wear himself out. They do eventually when they realize "Crap! This doesn't work anymore!". You have to be consistent in ignoring the negative behavior for it to work, however.

Just to get attention.. if this has happened in the past and he was given his way afterwards; this will cause this action to repeat... This action will stop it does not cause him to get his option...

the child's spoiled...

stop giving him what he wants and maybe he'll quit acting like a brat...
