The Witcher 3 - how to save the baron, his wife and children

Passage of the quest "Family Affairs" to a good ending in the role-playing game The Witcher 3: Wild Hunt

Surely, many of you, during the first playthrough of the game, faced a problem in the Whispering Hill location, when, due to one wrong decision, you ruined several lives and destinies at once. In this guide, we'll show you how to prevent the Baron's wife from turning into a monster, as well as how to save the children from the witch's trap.

What is needed to save the Bloody Baron, his wife and children

1. You must support the baron in dialogues and decisions, or remain neutral. Otherwise, all the points listed below will not be decisive.
2. The baron's stillborn child does not need to be killed! Do as the baron asks: put him out of his misery and turn him into Chur.
3. Visit the location "Whispering Hill" and talk to the spirit in the tree before you talk to the witches and take the quest to destroy this very spirit. You should not make a decision the first time, because this will lead to the disappearance of children and the transformation of the baron's wife into a monster. Answer the spirit: " I should think ."
4. Talk to the witches and take ?A gift to destroy the spirit, then return to it and disenchant it with a special ritual with a black horse, feather and bones. IMPORTANT. If, upon returning to the spirit, he did not say " The children are in danger ...", then you did something wrong and you will not be able to save the children!
5. If you did everything right, go to Oxenfurt and talk to the baron's daughter. Return to the Bloody Baron himself, tell him about his wife and daughter, then just follow the quest " Return to the Crooked Marsh ". Since you rescued the spirit, he will free the children, and you will only have to get rid of the demon along with the baron and his daughter.

UPDATED (Thanks to demandred):

1. You can start with the quest with Keira, but after that DO NOT GO TO THE SWAMPS IMMEDIATELY.
2. We make a chain with the baron until Igosha turns into a chura and the moment when he takes us to the fishing hut.
3. We go to the whispering hill, we talk with the spirit, we do not promise him anything.
4. We make a chain with witches all the way. We save the spirit.
5. We go to Oxenfurt (we won’t get there without a letter, one of the ways to get it is to tell the baron that his daughter is alive and in Oxenfurt - this is acceptable). Pro??nnu at this stage do not say anything.
6. We visit Tamara, tell her about her mother.
7. We return to the baron, tell him about his wife.
8. We go to the swamps and meet Anna there - outwardly healthy, but gone like a cuckoo. If you break the sequence, she will be a monster that can be disenchanted as much as possible, but immediately after that she will die (standard walkthrough).
