This forum seems a better place to ask about what's going on than bothering the organisers at the moment. They have enough to do. So far the info on the website is fairly general e.g.
"WHAT ABOUT THE KIDS?
There is a full daytime and evening programme specifically for children at very reasonable prices. Children are also very welcome (with well behaved parents) at most events although sometimes we need to ask that you make other arrangements for them - especially for late night events. There are also a number of family events."

There is also a very long list of artists appearing.

Some of those artists post here, so we can find out more about what we have to look forward to (I now have 2 MUSTs before the programme comes out).

BTW I like the idea of chidren being welcome with "well behaved parents". A child taking part under its parents control is gaining a folk heritage, a toddler wandering uncontrolled on the dance floor is a danger to all, and it is the PARENTs whose behaviour needs to improve.
A well behaved parent will find suitable events to take or send her child to, as Mrs. Duck is trying to do.
