Head Banging GS

Has your grandson had a medical check ( not only HV) to exclude any physical cause for the head banging JulieM123. If that's all clear then there is helpful advice on here. It's a common problem and usually as MiniMoon says, self regulating.

Here is an article about head banging

My youngest grandson used to head bang. It was horrible while it lasted. They lived in a house with a tiled hall floor, and he used to bang his head there!? It is upsetting for those caring for him, but it is a phase some children go through. The thing is to try not to worry. Head banging is "self regulating" behaviour, and he will not bang his head severely enough to cause any damage apart from an odd bruise, he'll pull back from actually hurting himself, although it won't appear so.
By the time my grandson was about 3 he had outgrown the habit. My DD tried not to reinforce it, by leaving him to bang his head, it's a hard thing to ignore though.
To reassure you, DGS is 6 now and a very intelligent little boy.

No Izabella she doesn't offer anything like that and wasn't really constructive on giving strategies to help them. My daughter is so sad and it's affecting all of us because we don't want him to hurt himself and we want to understand why he does it. It's not as if he wants to sleep with them in their bed and get out of the cot as he just messes around if they DO take him in bed with them. Lack of sleep and worry is making their lives a misery and I feel so utterly helpless to suggest anything other than padding the cot or wearing a helmet (which GS wouldn't tolerate)

Its amazing isn't it. They have it down to a fine art. Loud enough and alarming enough to get a reaction (and bruises), but never hard enough to really hurt themselves. As you say easy to ignore/distract during the day but harder at night. However, it is the reward of parental attention that reinforces it. Does the HV know of - or run a sleep clinic?
