I would recommend that the bylaws specify that meetings are for adult only members and that children are not allowed for liability reasons.
For those that have an interest to attend and have kids without support/ babysitter - Thank them for their interest and tell them they will be welcomed once arrangements are made. I want to enjoy adult friendship at the guilds and not have to strain my hearing or my eyesight to see if a kid is getting into all so many things like pins, scissors, rotary cutters, cords, and such. A person can not watch their kid and see at the same time. It's a liability waiting to happen.
