I belong to Children's Writers and Illustrators of British Columbia (Cwill BC). In fact, I'm the treasurer. That's not the sort of job they should have given someone who does math by connecting dots, but I'm thrilled to say that so far we've remained 'in the black.' That means we don't have to file for bankruptcy, so I'm doing okay.
Cwill is a big family (well over a hundred members). We talk to each other at meetings and through e mails. We ask each other for advice that relates to writing, illustrating and publishing.
'How much did a pint of milk cost in 1884?'
'Were any of the roads in Paris paved by 1322?'
'Where can I find a medieval Spanish lullaby?'
'Does anyone know a good literary agent?'
Questions like that come up all the time.
It helps to have a writing family. There are at least two writers I know that I 'talk' to regularly by e mail. We give each other advice, tips, suggestions and encouragement. Now and then I cry on their shoulders ("Boo hoo. How can I make this plot believable? Why won't this character work?") Once in a while they cry on my shoulder. Every writer needs that kind of support.
Do you have friends who write? Maybe you could get together sometimes and discuss the problems you have as writers, or the things that work for you. Help each other out. Everyone knows something that other people don't know. Share. That's what families do.
