DS (9yo AS) and I are going to visit family abroad in a few days. DS gets very travel sick and perhaps more significantly gets anxious about doing so. The journey will involve an hour long flight and an hour long car journey- nothing huge but it's massive for DS. we haven't done this trip for 3 years but it means a lot to me try to do it. DS is ADAMANT that he is not going. He can't stay home with DP coz DP cannot take tine off work, so if he refuses on the day then I'll have to miss the trip too. I've done a social story. I've shown him, and he has tasted, the anti-travel sickness tablets. He knows he can watch a DVD on the plane, or listen to music or whatever. He knows on the car journey we can stop every 20 mins if need be. I've shown him photos of the family we'll be seeing and who's collecting us at the airport. He's now refusing to discuss it at all and insists he's just not going. I've only got 4 days left, flights are booked etc obviously. Any suggestions of what else I could try?
