Parents who fail to attach? Attachment is not yes or no; there are degrees. And there are parents, when they have children, who keep doing a push-pull, who will seek affection and then reject it, who reach a point that they don't understand this, and feel it's their fault. They in some ways feel that they've failed, and then they don't want to invest any more. There are struggles in parents related to attachment, especially with kids who resist it.
