How can we ensure my child's emotional well-being and comfort during treatment, especially considering their young age?

As a parent of a child undergoing pediatric cancer treatment, one of my biggest concerns is how to support my child's emotional well-being and comfort throughout the process. Cancer treatment can be challenging for anyone, but considering my child's young age, I want to make sure they feel as safe and secure as possible. Can anyone share strategies or resources that have helped children cope with the emotional aspects of cancer treatment? Whether it's play therapy, child life specialists, or other approaches, I'm eager to learn about ways to help my child navigate this difficult journey with resilience and support.
