You will want to take along some ways to keep your autistic child entertained while you are actually traveling. Take books they enjoy reading and listening to.. Consider not worrying so much about how much time they are on their devices. Take snacks that won’t be so messy while you are on the road. Take coloring books too.
Take something from your doctor stating that your child is autistic. You may be surprised by how many times that will come in handy.
As you begin preparing for your trip, you will want to share some social stories with your autistic child. This will help them understand what you are about to do. Start sharing these stories at least week before you are to leave.
