"Mothers randomized in the intervention group will receive an educational session based on the motivational interviewing (MI) approach with a research assistant (RA). The RA will have first received a standardized training session on the content and techniques of MI.~The MI intervention will be carried out in simple and understandable language in order to allow discussion and questions from parents rather than provide prescriptive and direct information. The intervention will last approximatively 15 to 20 minutes."

Mothers randomized in the control group will receive a locally information flyer on childhood vaccines without any oral explanation by the research assistant.
