Because my son has heightened issues with sensory issues, being hungry is a big trigger for behaviors. So when he was young, even though he could not articulate his needs, if he was hungry, allowing him to be able to feed himself was a huge help but it had to be healthy foods. Like he knew that eating something unhealthy would not make him feel better but having access to foods high in protein, like hardboiled eggs, cheese, maybe bananas, anything, and fruits that he could feed himself that have access to helped a lot to make him feel better. So even in travel, you want to have like a to go bag that might have snacks in case you are going to be delayed mealtime. Then, he would have something that he could feed himself that would be healthy and it would make him feel better and we would have fewer behaviors.
