Hello,
My 20 month old has begun doing the same thing. I go to an amazing therapist and have been talking to him about this and he thinks it is fairly normal during a certain age but how you respond can determine how long it lasts and whether or not it turns into something bigger as he gets older. He gave me some good advice on how to handle the situation. First of all DO NOT let him do it. Stop him from hurting himself. He can cause damage to his head and neck. Also tell your husband NEVER to yell at him about it. What I have been told to do and it helps the situation is stop my baby first. Drag him away from whatever he is banging on, put your hand in the way, whatever you have to do. Then hold him, even if he struggles. Hold him, stroke his hair, back whatever is calming to him and talk to him. Ask him why he wants to hurt himself when he is upset. What he is so upset about, what he needs. Encourage him to think about why he does it. Give him some words he can use to tell you what is going on with him. Even if he does not understand or can't answer. Eventually he will and you are planting the seeds of communication and caring with him. Don't respond negatively to this and don't ignore it. You will only make the situation worse and possibly turn it into a bigger problem in his future. Best of luck to you.
