Where is that switch anyway!?

This sums up one of my concerns about my son...

"He didn't learn the same. WHEN he learned, he learned FASTER, and deeper than any of the kids we were around. But he also didn't learn consistently like they did. It was like someone flipped a switch and he went from dark to lit up 100 watts all at once. Seeing that he learned so fast really didn't make me worried. (...) What did kill me was waiting for him to get that switch flipped. It never seemed like it was up to me but rather to some random timer switch." from Building Wing Span

Raccoon absorbs information, and remembers it, in amazing quantities, but his perfectionism wars with the flawed repetition necessary for mastery. At this point, I'm not sure when (sometimes I whisper to myself if?) he will speak Spanish (despite living in a fully bilingual home), and many other things that he is not just uninterested in, but actively dislikes. Letters also come to mind.
