That's great. I think this book has some good advice for you, even though it's a little dated. I don't really know of other books as I'm an adult and this book came out when I was a kid. One of the really important points the book makes is self-care as a parent. You have to have a support system that understands you. Another really important point in the book is the agency of the child, in other words, the capacity for your kid to make their own decisions instead of putting them into a box.
It's great that you go to monthly meet ups! Feel free to continue this chat if you have any questions.
