I agree that diagnosing a two year old infant with a clinical mental illness is ridiculous. Anyone who has raised children knows that all 2 year olds are bipolar in nature. Given to great mood swings.
Psychiatric professionals rarely, RARELY will commit to a firm diagnosis before age 18.
I think it's clear from the articles about this family that there was mental illness evidence ... in the parents.
But, viewed from a bigger window ... I think that this is the current trend in our country. We pop a pill for everything. EVERYTHING.
Blood pressure too high? Pop a pill instead of dieting and doing cardio exercise.
Diabetes? Pop a pill instead of watching your carbs.
Not happy in life? Take a Prozac instead of mentally assessing life and making healthy life changes.
Got an active two year old? Diagnose as mentally ill and put her in a drug induced la-la-land.
I don't know why this story takes us so by surprise.
Next time you turn on the tv, notice how many pharmaceutical advertisements you see. And they are not directed toward health care professionals .. they are directed toward Joe Consumer. That way we can diagnose and medicate our own ills. But heh ... thats another post for another day.
