Diagnosing conditions such as ADD is a very complex thing, and it is done by medical professionals who are specialists in the field. There is no way that a MCHN would have the knowledge of a condition like that, nor would a child that age be able to be diagnosed.

Your DD sounds a lot like my DS1, who we are on a list to have assessed now that he is (nearly) 4. DS1 was also early with milestones, rolling at 7 weeks, crawling at 5 months, walking at 9 1/2 months. He also could read all the letters of the alphabet by 19 months and can now read really well (this is self-taught too, he learnt by pointing to letters or words and asking "what's that"). He also lacks concentration to do things like eat or dress himself, without a lot of nagging - he is too busy counting, spelling, asking questions etc. But TBH I don't think he has ADD - he is able to concentrate on things he is interested in, just not on mundane things. Also, despite his early milestones, he is now behind with gross motor skills and lacks confidence in his physical ability. The reason we are having him assessed is to rule out ADD and autism spectrum issues. There is such a fine, blurred line between being bright and being ASD that it is really difficult to determine what is what.

I would wait for at least a year and a half before worrying about any of these syndromes. A lot will change as your DD gets older, and only time will tell whether there are any areas for concern or not. And if there are concerns, there will be plenty of time for assessment later. We are only doing it now as it might impact on school choice for next year. GL hun.
