Congrats.

As an IEP parent for two years, I can tell you that we still struggle. But this is a good first step. Most teachers and staff will try to follow the IEP. Some won't and you'll need to address that. Some people still won't appreciate your child's disability. But an IEP is a very powerful thing to have, and if it is what's best for your child, then I see no shame in it at all.
