I work at my older kids' school and have been very open, including sharing my blog details with other staff. The school has been amazingly supportive of both me and the kids. My youngest is at primary school and I contacted both her teachers last year and this year (I was diagnosed just before the end of the school year). I also made sure that my kids felt okay about sharing the info with friends and as a result have had contact with other parents re: diagnosis. One of the things I talked about with my kids was that their friends or others may say things that were insensitive without realising and if something upset them they should immediately talk to a teacher and to me.
