Don't ask, tell. Don't start your requests with "Would you mind?", or finish them with "O.K.?" Instead, give clear and succinct instructions like “Please pick up your coat from the floor."
If your child doesn’t respond to your first request, try saying it another way. Kids respond differently to requests so saying things in different ways may lead to a better response from your ADHD child than simply repeating the request again and again.
Insist on eye contact. When you look at each other eye-to-eye your child can't ignore you and will listen to what you’re saying. Ask your ADHD to child look at you when you explain why a certain behavior is bad or when you are requesting a change in behavior. like waiting patiently or cleaning up a mess.
