Ds has this new habit of getting down on his hands and knees and butting the floor with his head. He does this if there is any upset or anyone disagreeing with him. He also hits his head on any surface including me or will hit himself on the head. it is really horrible to watch. I was trying to ignore it and not reward the behaviour with attention but today I have asked him to stop it. Not effective really.
Does anyone have experience of this or any tips to nip it in the bud? Or do I need to just wait for this phase to pass?
TIA
