But what is developmentally ready for a twice exceptional child? While he was still 3, my son was doing Reader Rabbit First Grade at home, but because he has motor dyspraxia he couldn't color in the lines very well. He said he could do it but it took too long and he hated it. The kindergarten teacher felt was important enough to recommend holding him back a year and didn't feel that it would hurt him in any way because he didn't need to learn anything. The problem was, my son wanted to learn.
