when should i tell my students i'm taking maternity leave next nov./dec.? do i tell them before or after they sign up for next year? i WAS planning to tell them at the year end recital in june, but it may be pretty obvious by then. anyone with experience in this situation? were you afraid of losing students?

p.s. i may be wanting to pick your brains about how to keep my students busy over this time as well. ie. stuff more interesting than just theory sheets...
