looking for a play with a child

I'm currently searching for a play i will direct for my honours yr which includes a lead role as a child eg -under 13 yrs. I would prefer it to be Aus but that doesn't really matter, but it must be a play - not a musical!!! Has anyone got any ideas, i've been looking, but i can't find anything i enjoy. I found plenty that are for adult actors to play to children, or really bad quality scripts for the class room, but i'm really looking for something that is quality, includes children and adults and is aimed for adults.
However time is running out, so any suggestion will do :)
thanks
Vanessa
