At the moment the TV is fine- he loves it and always has, he has always hated natural sunlight in his eyes and this has always triggered a meltdown.
He used to stare at lights in the supermarket and has never before bothered about lights inside the house.
I did wonder if it was transition from dark to light, so I have just tested the theory by turning the lounge light on whilst he was engaged in his NG toys and he screamed- so I think it is the light.
He is under responsive to sound - well used to be and does not startle or blink at loud sounds or turn to sound (Hearing is fine).
He does have major sensory difficulties and we have been working on these for the last 15 months with a private OT- so I am trying to contact her as he has regressed to how he was when he was just over a yr old and now has the physical strength to resist- making shoes/socks/clothes/car seat a major battle- and meltdowns lasting so much longer.
I am using spinning and other bits of the sensory diet- I am going to make a pecs card of the light to try and warn him, but he has very little receptive language adding to his behaviour. I have not got a blanket but I have got a weighted lap cushion so I am using that to try and calm him but I will now try and calm him before we start something distressing.
I just have no idea what has triggered this massive bout of sensory disregulation :(.
He has just started to say No - although much as he says it he will say it to anything and everything even if its something he really wants - but this is progress to us and he has started mirroring words and pulling us to things he wants- so I don't know if this development has sent his sensory world haywire!
It has been going on for a week now this dramatic change in behaviour and I have tried calpol, nurofen and even taken him to the drs as it is such a backwards step- but all the dr can tell me is that there is nothing wrong with ears/chest/temp ..
He is ok and quite happy when left to his own devices he will spin happily and play with his NG toys- so I am thinking its not medical.
He sometimes wears hats so I will try thats.
Thanks so much for your replies - it really helps to have others insight and ideas when I am trying to run in water with him, xx
