Thanks so much for this, so helpful.
When we started going down the diagnosis route and I was doing my research I read up about Sensory Processing Disorders and could relate this to DS1. However, after diagnosis, it all became about communication, visuals, play, preparing him for change etc. I kind of put sensory issues to the back of my mind and I guess 'dismissed' them.
However, recently I have been very confused and getting a bit down trying to understand DS1. He doesn't appear to need 'preparing for change, need to know what is happening next' etc. He has always been quite flexible - doesn't need strict routine, loves going on holiday, doesn't mind using different bowls/cutlery/toilets/stopping off at supermarket etc. He has always happily gone into new play centres, swimming pools etc. Don't get me wrong, once he has had enough, he has had enough and we have to leave.
He doesn't like confined crowded places and tries to run off. If it is a large space he seems to cope with it, eg. going to a party is fine but getting him into a small room for food is a no-goer. Taking him to a friend's house is fine but then if lots of people are there he wants to go upstairs and play in a bedroom. He does the feet in the back (arggh, I have a thing about feet!). It is a complete nightmare trying to get him in bath now, cut his hair, nails, wash him. He has been poorly recently and taking his clothes off was stressful for both of us (hasn't been like this since a baby).
I am struggling to get him to nursery at the moment, no matter how much I prepare him (he simply doesn't want to go). I have noticed that if somebody says 'hello or good morning DS1' when he walks in he throws himself on floor. He comes round after a few mins and then he is fine.
Sorry, I am waffling on now. I am going to get the Out of Sync Child (to add to my collection - just got the More than Words book!).
I am going to look into getting a private OT to assess him too.
