Your Body Belongs to You (Lucía Serrano)

This is the best book I have come across that teaches children to understand personal boundaries and prevent unwanted behaviour and contact in a very developmentally appropriate manner. It does a great job at breaking things down in a simple yet clear way. I’m unsure how to find the book in the US but can be found in Europe in Spanish and English.If you are looking at books in Spanish, the rest of this author’s books are amazing.
