I am comparing kids vs adults, not people with ADD and without. Kids can react differently than adults. The source of that was my Uncle, which was confirmed by my children’s pediatrician. I don’t know the literature on it, though.

It doesn’t seem like good advice to try it on yourself to check if it’s good enough for a child. That was the point I was trying to make

Though I agree trying it yourself provides little useful information, your broader statement is still confusing.

An individuals reaction to stimulants varies based on a large number of factors. Though age may be one of the factors, it is not a large enough one to say "children react differently than adults." If they did react differently, stimulants being common for both children and adults with ADHD wouldn't make sense.

I mean no disrespect here, but might you have misremembered things doctors said about "your children" and changed it to all children? As people with ADHD do generally react differently to stimulants, with drowsiness being a common side effect.

As I stated, some children react differently. An example is with Benadryl. Some children get a lot of energy and have an opposite effect.

With stimulants, I'm not sure if it's some or all children, however, my point was to apply a bit of skepticism towards trying medicine out on yourself as a filter for its efficacy on your child.

Edit: Here is a link for an example. It may actually be stating that stimulants in children do not have a paradoxical effect. I'm too uninterested to research this, but would be interested in a professional's opinion.

It's still not "some children," it's "some people," though I must point out that you did not say some children. Without the "some" it's a much more troubling statement. It seems to be the same for Benadryl, as the only scientific source for any paradoxical effect I can find only saw it happening in three adults.

I'd take it the further step and say "don't take medicine prescribed for someone else."
