OBJECTIVES to build and validate an educational booklet to promote the involvement of parents in labor and birth. METHODS methodological study developed in five stages: situational diagnosis; bibliographic survey; construction of illustrations, layout, design and texts; content and appearance validation by judges (25 experts) and calculation of the Flesch Readability Index; and validation with the target audience (12 parents). A minimum Content Validity Index of 0.80 was considered. RESULTS the booklet was entitled "Father Presence" and was developed in 11 topics. In Content and Appearance Validation, the Validity Index obtained an overall score of 0.97. Cronbach's alpha was 0.92, indicating excellent reliability of its content. A global score of 74% for readability was obtained, considered easy to understand. CONCLUSIONS the material was successful in the validation process, and it can be recommended for parents to use it during the prenatal period, promoting the inclusion of the partner and preparing them for labor and birth.
