The child (1) had investment income of more than $2,000 and (2) was under age 18 at the end of the year; was age 18 at the end of year and did not have earned income that was more than half of the child's support, or was over age 18 and under age 24 at the end of year was a full-time student, and did not have earned income that was more than half of the child's support.
