Yes, I think it is a tricky situation. I think it was a behavioural/speech type issue it is much harder, as it can be very subjective with many variables. A medical issue is a little different, but comes down to how well you know the parent, your own knowledge/experience and of course, how you approach the subject. I have broached these type of things before with close family, but have chosen my words very carefully and it has always gone down well (I think ) however I think it helps that I work as a health professional. I would like to think if there was something I was missing, then I would like a family member to mention it, as I would know they have my childs best interest at heart. What I choose to do with that input however is my decision .
