Question: When are fidgeting, spacing-out, silliness, lack of focus, inattention to detail, emotional overreaction to 'change' and hyperactivity "normal" in a child?
Answer: Apparently, it depends on if those things are causing said child to struggle at school, with friends or at home.

Question: If you find it necessary to attempt to address (i.e., "fix") those aforementioned behaviors, and following an in-depth conversation with an "expert", the first thing said expert(s) identify is ADHD, followed by a suggestion of medication, what should you do?
Answer: I. Don't. Know.

This is sensitive, because I'm not really seeking advice, per se, and my wife straight-up told me that she really doesn't want to tell our family about this (though my mother already has some knowledge of it). However, I know we have lots of parents here, with a pretty wide variety of experiences - both professional and personal - who might be willing to talk about what they know, think they know, or otherwise have an opinion on.

I have a child with a lot of intelligence, curiosity and quality interpersonal skills. Great kid - caring, empathetic and friendly. Also, this kid cannot sit still in class, stay on task, pay attention to things that aren't of interest, etc., etc., etc... to the point that two-years worth of teachers have spoken to us about her inability to complete tasks on time, without continuous prompting and repeated reminders. No surprise there, because tasks like getting ready for dinner, bedtime, breakfast, school, play, bath .... all take much longer than they should, and frequent prompting typically results in tears and overreaction (on my/our part as well).

We want to help, and want help, so we sought out expert advice. I trust experts - attorneys, physicians, accountants, mechanics, etc. I look for the 'best' and trust what they tell me. That initial meeting went well, confirming (but not formally diagnosing) what we'd already considered. However, when the inevitable discussion of options to address the concerns led to information about medications, I immediately felt a panic - "No! Not my child! I've seen/heard too many horror stories about [insert whatever 'brand name' stimulant or anti-depressant(!) comes to mind] to be giving that to my child!" That's all the farther we've gone; still working on a formal diagnosis, but I'm feeling conflicted about what comes next.

What do ya got for me?

I mean, c'mon, even the label warns to "Keep Out of Reach of Children" !!!
