ds is 6, just recently diagnosed with autism. he attends a special school. during last year, he was removed of school transport due to making himself sick. was allowed back on, but had to be removed again as this kept happening. when he started back to school in sept, he was on a bus by himself with just an escort, and on the way home with a few other children. All was going fine until 2 weeks ago when ds made himself on the way home. this happened maybe once a week. then everyday for a week, and only on the way home. this week, transport decided to stop transport on return journey, and send him home in a taxi with an escort. all fine on day 1. ds was then sick on way into school everyday this week so far. and was sick in the taxi on the way home. there isnt anything wrong with ds, he doesnt have a tummy bug or anything. previously making himself sick was down to attention seeking behaviours. but he has 1 to 1 attention on the bus to school and taxi home. i really am at my wits end with this. there isnt anything i can do on transport, i dont know why hes doing it, and he cant tell me why. has anyone else had any experience of this, or suggest anything i could try? any help would be greatly appreciated.
