Traditional Approach

The traditional approach is to give the child the last name of the father. 


The pros of the traditional approach include continuing what may be a typical tradition through generations of your family. This tradition may be important to certain family members. It can also be a simple way to identify your family and have your family recognized by others if there is one unifying last name in cases where the mother has taken the last name of the father as well.


The cons of the traditional approach is that this completely disregards the mother’s typically tremendous role in a child’s life by not including her name or lineage. This approach can also prevent the maternal surname from being passed on at all in the case of some families. Lastly, this approach does not allow for creativity or non-traditional intention in the choosing of the last name.

Hyphenated Last Name

The hyphenated last name approach uses both the mother and the father’s surnames combined with a hyphen.


The pros of the hyphenated approach include equally representing both parents and their lineage in the name of the child. For some families, this may feel like the most fair approach to honor both parents and both sides of the family.


The cons of the hyphenated last name include what might wind up being a very long last name for the child. Also, the likelihood of the child one day passing along her full last name is not strong as it will become more complicated when combined with another name if she chooses to do that as a parent.

A Last Name as a First or Middle Name

Similar to the hyphenated last name, one parent’s last name can be used as a first name which has become trendy, or it can be used as the child’s middle name.


The pros of this approach include being able to have both parents’ names represented within the child’s name in some way.


The cons include that one name will be more prominent when chosen as the last name.

A Last Name Created by the Parents

Parents can choose to create a last name for their child or for their entire family to represent their values or how they see their family.


The pros of creating a new last name include the fact that the parents have creativity and choice in the selection. A new last name can represent a new beginning for a family which can be powerful.


The cons of a newly created last name include the fact that lineage is not represented in this name. This choice may also be difficult for some relatives to understand.

The Mother’s Last Name

In the same way that the father’s last name has traditionally been passed down to the child, parents can choose to do the same with the mother’s last name.


The pros of this choice include beginning a tradition that honors the mother and the maternal line. This can also be a unifying choice for single moms creating a family.


The cons of this choice include recognizing only one parent and one side of the family.
