How do buddhists celebrate birth?
Often during the naming ceremony, a Theravada Buddhist monk will bless the baby and name her. The name chosen by the monk is often based on the day, month and zodiac year of the baby's birth along with the baby's character. Sometimes the name begins with the letter that is blessed for the day of the week on which the birth occurred.
Sometimes parents (especially those from the West) will prefer to name their baby themselves. When naming a baby, Buddhist parents will often choose a name that is tied to the day, month or season that the child is born. It is common to choose a name that begins with the same letter or that rhymes with the name of a mother, father, brother or sister. Finally, parents may opt to name their child after the sun, moon or even a flower.
