A book titled 'What Does LGBT+ Mean?' has been distributed to over 800 schools and teaches children that a person's sex is 'assigned' to them at birth as well as introducing them to the 'definition' of male and female.

The book is said to be aimed at children aged eight to eleven on the company website, where the book is described as exploring identity, "assigned sex, gender, love, sexuality, discrimination, privilege, allyship, pride and more.""This is going to be a book that will make a big difference in the lives of countless young people."The book tells children that gender is a 'sliding scale between male and female' and when you are born, a doctor or nurse gives a baby a label based on what they can see.'What Does LGBT+ Mean?' is written by diversity campaigners Olly Pike, Mel Lane, and her son, James Canning. The group are encouraging book owners to donate their copy of the educational book to local primary schools.

In a section titled 'assigned sex' it reads:

"A person's gender is who they feel that they are, e.g. male, female, both or neither."

"Gender is usually something a person just knows about themselves, although it can also be something a person discovers about themselves as they grow older. Most people's gender will be the same as their assigned sex, but this is not always the case for everyone."

The book continues by explaining that the 'sliding scale between male and female' is "shown with labels in between male and female, including mostly female, partly female, both or neither, partly male and mostly male."Speaking to The Times, Helen Joyce member of advocacy group Sex Matters said that nobody is 'assigned' a sex: 'I've given birth twice and both times I knew what sex the baby was at 20 weeks. It's just absurd.'
