When a child is born, the first person to hold and kiss the child is the mother. When a child grows and commits to another person, or in the case of gender transition to their new life. It is perfect that the mother is the last person to kiss their child before they move on to the next stage in their life.
The variation on this themes in a gender transition ceremony is where all of the friends and family kiss and / or hug the individual to show love and acceptance of them as they truly are and as who they wish to be known as.
