So many skills to learn and only one life to get it right?
The manual never goes out of date, school is always in session, and the Teacher is always available for questions and answers.
Hope that you and H can carve out some time for just you two. I know that the kids can take a toll, but remember, they have a vested interest in this too.
One note of caution for H going to therapy - don't expect an overnight transformation of behaviors. It will take time for H to develop new ways of handling things. Keep your expectations low initially.
