Covert incest is when an adult (usually a parent) acts very close to their child in a way that crosses normal boundaries. It includes things like talking too much about adult subjects, and giving them cuddles and affection that are inappropriate. It can also include things like expecting the child to take on a role in the family as a partner rather than as a child, like expecting them to keep secrets, take responsibility for their parent’s feelings, and making them feel responsible for their parent’s happiness. Covert incest is damaging for children and can have long-term effects on their self-esteem.
