I’m aware this may be unpopular, but I think it needs saying.
Even when partners are kind and well-intentioned, repeatedly bringing new men into children’s lives creates instability that children did not choose. Children form attachments whether adults intend them to or not, and those attachments being broken can affect their sense of safety and trust.
In my view, adult desire for companionship should come second to a child’s need for consistency and emotional security. For many children, the cost of repeated relationship changes simply isn’t worth it.
I’m not saying this applies to every situation or that parents don’t try their best. It’s something people should think very hard about before introducing partners to their children.
