My son has thespian tendencies ...

[Quattrocento]

... and the school has suggested that I help him to develop them.

Any (polite) suggestions? Because I honestly have no idea about this.

A drama club, after school/weeend job. Something like stagecoach, only cheaper.

My son's the same, has a need to entertain.

how old?

He is 8. Just had parents' evening. They said we should do something...

Drama club. Ds1 (7) goes every Saturday morning and seems to really enjoy it. I never noticed his "thespian tendencies" until his teacher pointed it out when he was 5.

I spent years trying to calm ds's down. Don't do this, it makes no difference, it just makes like more stressful for you and your ds.
I'm now encouraging it!

Not stage coach

choir?
music?
drama club?

Have you tried your local theatre? Sometimes they have community childrens groups. They are free (normally) which helps.

Thanks for suggestions - will follow up. What's wrong with stagecoach?

Expensive, pushy, expensive, commercialised, expensive.......

There are alot of groups that do childrens drama classes for a fraction of the cost.
