That's my kid to a tee... he can eat sushi with chopsticks and do grownup jigsaw puzzles and pick up a bug with tweezers, but his handwriting is off the charts. I think i would be less worried if his other fine motor was poor!!
We watched "Spy Kids 4" a while ago, which I wouldn't exactly call an accurate portrayal of anything, but I liked that they didn't harp on about the kid's deafness, but that both the hearing aids and ASL were part of his special spy skills.
He's going to spend the summer at his old preschool, where all the teachers use ASL, 1 is Deaf, 2 are hard of hearing, and 1 is hearing, and the kids are a mix of hearing, hard of hearing, CODA, and Deaf. He was there from age 2 to 4 1/2, went back for March break, and is super-excited about going back for the summer. I was thinking about it last night, and wondering if maybe we should skip school next year and keep him in the preschool an extra year. Maybe he'd have a better time working on his handwriting if he wasn't tired from listening all day.
