Not my child. In wider family. They are non-verbal and will be 5 soon. They have moved from being very happily absorbed in solitary play to becoming a lot more energetic. This has involved pulling stuff down from walls etc, with quite a lot of breakages/damage.
The child doesn't understand that this is problematic. When he is spoken to in a special explaining voice - this involves sitting on a step, it's a sort of accompanied 'time out' - they just think the being spoken to is a game and they laugh.
Any ideas? The child's Mum is obviously very worn down by it all, at present.
