You may wish to ensure her preschool/daycare has books and toys at her interest level. Donating books and toys may be one way to do this. Higher level books and toys which are of interest to her may also attract other kiddos which is a plus in terms of your child seeing who else has an interest in these things, in other words who appreciates the higher ceiling and may be closest to her level.
You may also wish to look into your local
schooling options other than public school, and learn all you can about
advocacy.
