family in Tehran

Hello, I am looking for a family of expats living in Tehran. We are planning to move the coming summer to Iran with my husband s work. We have 3 kids 8, 6 and 3 years, and hoping we can have them in the french school.I would need the advices about the things we need to bring with us, things we cant find . (medicine etc...), also about life in general with small kids.
Thank you
