She is obviously going through a hard time but incredibly privileged to escape away to her parents alone.
Just a point on her post from yesterday evening saying that an anxious child has nothing to do with parenting and to look up window of tolerance theory if we don't believe her. Yes a child is born with a certain temperament but parents can do so much to help. The window of tolerance can be increased by a parent coregulating with the child. So being genuinely calm when responding to the child consistently will increase their window of tolerance and increase their calm. But we do have to work on ourselves to consistently respond in this way. This is basic psychology. It worries me that people might read her post and believe there is nothing they can do to help their anxious child.
