We were wondering what to share last year when DYS DS7 (then 6) started 1st, as well. Within a week or two after school started the teacher ASKED the parents to answer/provide certain info about their children...and then we shared. If you have a good teacher, they might just ask you...and that made us feel less pushy. Had she NOT asked, we may have shared at the first P-T conference, which is near the start of the year.
