What to bring?
The short answer is just yourself, with a willingness to listen to others without leaping into giving them advice.
How much you want to talk is entirely up to you.

We have spare chairs adn blankets.

Most of the kids love to play and explore, so old clothes and closed shoes for leeches and snakes is probably a good idea.

Dress yourself for the weather, dont worry about dressing "up."

Bring something to share for morning tea if you like.
