Also posted in Behav/Dev but posting here for the SN perspective. Hope someone can help!
dd is 4 (has dubious diagnosis of ASD) and has tantrums, usually at bed time. Always triggered by her ignoring clear warnings that she is behaving in a way that is unacceptable and there being a consequence.
For example, she would not keep still while I was cleaning her teeth tonight. so I warned her I would stop cleaning them if she didn't co-operate, she didn't so I stopped. Cue wailing and throwing herself around demanding that I finish cleaning her teeth (she'd cleaned them, I give them a brush round afterwards to check them so they were pretty much fine) I told her calmly that she'd missed her chance but she could still have some stories read to her if she calmed down. Then we had meltdown.
She needs routine and predictable consequences so when she starts shouting and screaming I go downstairs to remove the attention that she feeds off. I try not to shout at her. I make noise to reassure her that I'm still there but I will not go back until she has stopped shouting/screaming/stamping/throwing all her things around. But she doens't seem to get this and screamed Mummy I need you for at least half an hour tonight. I try to be quick to reward when the screaming stops but three times as I went to her, she got worked up again and it set her off worse. she just gets so worked up she can't get herself out of it. She knows she has to be quiet to get me to come to her but can't see why standing on the landing screaming "I AM BEING QUIET MUMMY" doens't have the desired effect (she is bright as a button when she's not tantrumming and we've talked about it when she's calm to try to help her to understand why shouting and screaming that she is quiet is not working for her)
She loves chosing a toy to take to bed (along with her comfort items) so I have tried removing this privelige. (I never make her have nothing) I have also tried confiscating toys and making her earn them back with good behaviour. but when she gets the red mist cause and effect have no meaning to her.
When she trantrums in public it's worse as I can't remove my attention so it lasts even longer and she gets very violent.
I need a better coping strategy but what?
