Amazing reading, Shelleycat! (and I'm not even Anthony! ha)
Anyway....being born with many 2's in my birthday and with a 2 Challenge, I have to say that you are right on about the discipline thing. Seriously - the "I am disappointed in you" thing is crushing - don't ever use it! A look that hints at something is much better. (!) I wonder if most 2-challenged children keep themselves in line for fear of not being 'good'...? hmmmm.
Fascinating that your 2nd born has 0's as his Challenges! wow. Such a divine number.
Both your children are Air signs....I may look them up astrologically when I have time...
