we are going on holiday abroad to a family wedding. Ds has autism and adhd he has been abroad with us and is excellent on the plane but this time grandma, grandad and loads of other relatives will be on the flight. I am worried that they will get him hyper and then his behaviour will get silly. He needs time to chill out on the flight without anyone talking to him which well meaning family wont give him. As we will be spending a lot of time with the family when we get there do you think it would be ok if we sat away from them on the flight ? How would you tell them I would just be honest and tell them outright dh doesnt want to upset them. The thing is we have another trip just the three of us in october so I dont want ds to get into any bad habits on the plane otherwise it makes it hard work it took us years to get him this good on the plane and I dont want it to be spoilt.
