"Among other things, we talk about the difference between good and bad secrets. The bad secrets must be made unsecret, says Johanna Pettersson Östlund, who is a counsellor at Södermalmsskolan.
The initiative for Focus Week comes from Save the Children and aims to make it easier to talk about sensitive topics and to prevent violence and abuse.
Aimed at primary school
Initially, the initiative was aimed at the second grade, but for a couple of years now, Stopp! The My Body! week has become a tradition for all grades in primary school.
"These questions are very much alive all the time, but it will be more concentrated this week and it is usually appreciated by the children," says class teacher Cecilia Ström.
