As parents, we prepare for the worst and hope for the best. When you have a child with autism, you always need to think about what can go wrong. It's important to know the triggers that send your child into a tailspin. For us, it's a sudden lack of WiFi. I'm always ready with a hot spot (thank God for modern technology!) to prevent a melt down. I also travel with an extra bag full of his favorite snacks, cleaning wipes, extra shoes, shirts, and pants. Potty accidents do happen, but he also might find a puddle that has to be jumped in. You just never know. Also, before we go anywhere, my husband and I always make a plan and decide who will leave with him if he becomes overly stimulated. This makes any situation that comes up a bit calmer. Bottom line, you need to be a planner.
