It's hard I know. My DD(now 9) did the same thing at preschool. As soon as she realized she was the only one who could read and write, all of a sudden she forgot how. She was SLAYED and CRIPPLED by perfectionism for several years. She still is sometimes stymied by it, but she's much better. My solution was to (gently) push her out of her comfort zone, but not until grade 4. Maybe I waited too late... I don't know. All I know is that she is more relaxed now, which is nice.
Hang in there... he'll be ok
