"just give them a long stick to poke the fire and they'll be fine "
Not at my fire they won't

Kids waving smouldering sticks around will get told off, and any parent who complains will be asked bluntly, "Where were you ? "
Generally the kids at the meet ups and the Moot have been incredibly well behaved,

and they are aged from literally a fortnight old, to teenagers.
Basically, your child is your responsibility.
It's a family friendly site with a lot of people there. It's expected that fires aren't to be played with, other people's tools are not to be touched, and that other folks tents, tarps, hammocks and kit are not disturbed.
That's it really

What a child does at their family camp area and fire is up to the parents.
If your toddler really is a handful, then yes, I too would suggest attentive parents and reins
I'm presuming here, but on the balance of experience I'm pretty sure I'm right, that you have childproofed your home. Folks come to the Moot to relax, learn, teach, enjoy the woods and the seashore, chill out in like minded company; and they don't childproof their lives.
We do leave tools lying at hand, we do leave camping equipment sitting around the fires, we do leave our tents and hammocks unattended when we're elsewhere on site.
I'm not trying to be offputting, many parents bring very young children along and have a brilliant time

but the onus is on the parents to keep them safe, not on other folks to make the site safe for the children.
Kids aren't stupid though, they learn good practice very quickly

Courtesy starts young

no reason you and your child shouldn't have a great time on site too
cheers,
