This document discusses relationships and how they change over time. It begins by outlining key relationships in a person's life from birth through childhood and into adulthood. [1] Family relationships are the first and most important, starting with parents providing physical needs as infants. [2] Relationships gradually expand to include other family members, then friends through playgroups and preschool. [3] As people age, romantic relationships may form, which can lead to new families being started. However, relationships require work to thrive as situations, roles, and responsibilities change over time.
