I don't see anyone here diagnosing the OP's child with ADHD/ADD, where is that?
What I see is people suggesting it as it chimes with our experience of parenting DC with ADHD, or of having it ourselves, then trying to correct misinformation about ADHD.
Where it got into a debate with the OP was when she said no, her DS couldn't possibly have ADHD, but it was clear she doesn't understand the condition.
The to and fro on ADHD could have been avoided like this:
OP: "My DS loses and breaks stuff" stuff
PP: "sounds a lot like my DC with ADHD / dyspraxia"
OP: "Oh really, that's not something I've considered / know much about"
PP: Give info on our experiences of ADHD and why we are suggesting it as a possibility
OP: "Thank you for taking the time to post, that's interesting. Now does anyone have any practical suggestions about helping my DS to not lose / break stuff?"
PPs: Share suggestions for strategies
*
Instead, this happened:
OP: "My DS loses stuff"
PPs: "Sounds a lot like my child with ADHD / dyspraxia"
What the OP hears: "I am telling you, your DS has ADHD" (not what any of us have said)
OP: "No, my DS can't possibly have ADHD" (based on obvious misconceptions of ADHD).
PPs: try to dispell misinformation about ADHD and explain why it could be a possibility
Other posters: "Don't be ridiculous, DC with ADHD are like this" (insert more misinformation about ADHD here)
PPs:Try to correct further misinformation
New posters who haven't read the thread but are trying to help "Sounds like ADHD"
OP: Gets increasingly frustrated thread is about ADHD and defensive as she feels we are trying to label her DS.
