The book includes information about what is 'normal sexual behaviour' at different ages, divided into green, yellow and red areas. One example in the book of unacceptable behaviour is a child aged 6-9 who compulsively masturbates in public - the manual says that this is one of the cases in which parents need to act.
Swedish Radio News talked to child psychologist Marie Carlsson, who says that this kind of book is needed, "Unfortunately many parents just think that their child will get it from school, or off the internet, but as parents they have the responsibility to talk with their children about it."
Pelle Ullholm, at the Sexual Education Association, is one of the authors of the book. He says that many parents delay talkinga bout sex until the teenage years, which can have negative consequences. "In the worst cases it can mean that children are involved in things that they are really not comfortable with, and if you've not built up a rapport where you can talk about sexuality, then it will be harder for the child to fina an adult that they can share their concerns with."
