My 4 year old son most likely has SPD and he is being evaluated in June for that and will hopefully qualify for occupational Therapy, but there is a waiting list. We are planning a vacation for Oct or Nov of this year. He does not like any changes in his routine, has never been on an airplane, etc. Any tips for me? His issues are mainly tactile (oversensitive), plus oversensitive to sounds and smells. I'm worried he'll cry the whole time on the plane and won't sleep in a different bed. I was hoping to be working with the OT for a few months before the trip. I wasn't expecting waiting lists.
