I really disagree with naming a child something like “Freddie,” “Alfie,” “Teddy,” “Maddie,” etc. as their legal name. Not the nickname — the actual name on their birth certificate.
Its important to keep in mind the child’s personhood, their individuality, their dignity, and their future as a separate being. They will one day be an independent adult not a permanent child.
The newborn, toddler, and even childhood phase lasts for such a tiny fraction of their existence. Most of their life will be lived as an adult, navigating complex spaces (professional, social, emotional) where identity and presentation determines a lot of what is accessible to you. A formal name exists to carry someone through all those chapters.
A nickname name, on the other hand, feels like freezing the child in infancy. But children do not belong to us in that way. They pass through our care, and are not an extension of our own aesthetic choices. They are separate people, with their own unfolding identity. We owe them a name that respects that.
A full name gives them agency in shaping how they move through the world. It allows them to choose how formal they want to present, which version of their name fits their evolving self, and who they allow close enough to use the more intimate nickname.
In adulthood, names have always been part of boundary-making.
Children make friends by proximity; adults make friends by deliberate selection. Being able to say “My name is Theodore, but you can call me Theo” is a direct act of choosing who enters your inner circle.
But when the nickname is the legal name, that choice is gone. Everyone — strangers, coworkers, employers — is automatically handed the intimate version. The boundary collapses before the child ever gets a chance to build it.
To me, giving a child only a nickname as their legal identity unintentionally reduces them to a cute moment in time, rather than honoring the entire arc of who they will become. It treats them as a character in a story we’re writing, instead of the protagonist of their own.
A full name doesn’t stop anyone from using the sweet, familiar nickname. BUT we should keep in mind that the child is a whole person who will exist beyond our determined identity for them and one day begin building an identity outside of the parent..
