Don't lose sight of that relationship. Before you were a partner, you were a person that someone found attractive, vital and loving. Don't lose sight of that person. Get connected and stay connected with parents of children with and without disabilities.

Professionals can be very helpful and dedicated.
And some can be very off-putting. They can use fancy words and credentials to make you feel invisible. Don't let them.

Your personal knowledge of your son or daughter may be the most valuable information of all.
