I need coping strategies for little kids with anxiety please!

I work with pre-k / K age children who have been diagnosed with autism, many of which have high anxiety at times. I’m looking to expand my list of coping strategies for these children as wide as possible. I’m asking you to please comment with any and all coping strategies you’ve used or known to have been used with young children, and also please share this post so I can collect as many ideas as possible. I very much appreciate you taking your time to help me help these amazing children!
