Biological mother or birth mother refers to the woman who gave birth to a child. However, there are several synonyms to describe a biological mother such as natural mother, genetic mother, or biological parent. Natural mother emphasizes the idea that the mother is a mother in a natural sense, while genetic mother refers to the biological connection between the mother and child. The term biological parent can be used for both mothers and fathers and highlights the genetic connection to the child. In certain legal contexts, the term birth parent can also be used to describe the biological mother. Ultimately, all of these terms emphasize the biological connection between a mother and child.
