After having my child go through psychological testing a lot of great things came out of it.  The psychologist showed us his strengths, his learning style but most importantly he showed us a very high score on the self-esteem test.

Kids who think differently or have learning challenges are at risk for low self-esteem.  They notice they think differently than others and if their differences are not nurtured they are at risk.

So, get goofy with them, laugh with them, encourage their "wacky" thinking and never discourage it.  So many of our countries most successful people thought differently than their peers, they were encouraged by someone along the way, so be THAT someone to your kid !
