Traveling is always a good good thing, and yes, that is even true when you have a child who has autism. Traveling is going to get you away from your life and a lot of the stress related to that. You will want to start small and try to learn how your child travels. Does any of your family, or maybe a close friend, that lives an hour or two away? You may want to start your travels by going to see them.
When you do start flying, again you are going to start small, see what your child likes and what he does not like, and work your way up.
You will want to pick vacations that are likely going to appeal to your child who has autism. Don’t try a theme park when you are starting to travel. That is most likely going to be sensory overload. Camping might be a wiser idea..
