My 10 year old daughter is CM2 and hears many things at school this year. I am an open mom talk to her about everything but not knowing how far had evolved his knowledge on the subject of sex, I thought of Titeuf but she does not like that character. So I came across this book (the eye-catching cover). The comments appeared to me to match my search and I therefore confirm that it is very good and not shocking. The reactions of my daughter spend "yuck!" pouffage to laugh, she spent the first 3 days at first look images (lift vine leaves, for example) and then reading the small text while asking me questions. There was just enough explanation, neither too much nor too little.
