Is ADHD an Excuse for Bad Behaviour?

“Please can you tell me, is ADHD a behavioural disorder, in actuality? I want to know if my daughter is using it as an excuse for her son’s bad behaviour when they come round to ours.”

Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder. Children who experience it have difficulties paying attention, and/or controlling their impulses and regulating their behaviour.  It is a real disorder, not an excuse for bad behaviour. Children with ADHD want to behave well but they can’t. They do it the best they can. 

I encourage you to support your daughter. Being the parent of a children with ADHD can be very demanding, especially if your grandson is presenting challenging behaviour often. It is not surprising that parents of neurodivergent children are more likely to experience mental health issues and to leave their jobs. After all, these parents have  all the worries that all parents have, but at the same time they have to navigate diagnosis, treatments, medication, and doctor visits, while feeling judged and very often blamed for their children’s behaviour. 

You can make a big difference in your daughter’s life by supporting her and her son. Do not blame her for your grandson’s behaviour because parents do not cause their children’s ADHD. ADHD is real. It is not an excuse for bad behaviour. 

I hope this information helps. If you want to discuss this issue further in a 1-2-1 session, please get in touch with me.
