as this will only help him and you. Now you can effectively advocate for him and his needs. Some kids/parents go through life wondering why they are different and never having any answers (and that can lead to low-self esteem and more). Good for you!! Also, ADHD can be a gift, it really can. Another great great great book that I can't recommend highly enough is Dr. Sears The ADD book. Its so positive and highlights the strengths of having ADHD.
I know you are worried about having him label, but that label can get him extra support at school if he needs it (either under an IEP or a 504 plan - ask me later if you have questions about the school aspect of this). He may not need extra support now, but later he might (i.e. in middle school he may need a class on organization and study skills, etc).
Also, everyone has some aspect that makes them unique and areas we need to work on (some just don't have a name). We all have these things (I tend to be a perfectionist and will always be working on that aspect of me; my son has difficulty articulating his words; my daughter has challenges in the area of social skills, thus autism). We all have our strenths and needs, Ian's just happens to be in the area of attention. I am sure both you and your husband have areas you have always needed to work on too - we all do.
I don't want to downplay this diagnosis for you - because its ok to feel how you do. But I do want to highlight the positives for you!!
Heres the link to the book.
