Recommendations for kids

So as I approach 37 and I struggle to manage my mind and love myself, I wonder what exists for kids to learn these skills at a young age. Since I am into self help I’ll talk to my 5 year old daughter about loving herself and feelings, but how great would it be to work on these skills asap! Any recs? i never really thought about how cra it is that we are never taught how to manage our minds. I’m in the right place! Thank you!
