An example of a good birthday wish for a son is, "Every single day you’ve added something amazing to my life." Common elements of birthday wishes for a son from a father, mother or both include bits of nostalgia, sentiments of a life enriched by parenthood, and hope for the future.
When crafting a birthday message for a son, consider some past memories or events that carry some sort of significance, even if the details are seemingly mundane on the surface. For example, share a memory of a mess the son got into as a toddler, his first words or simply the feeling of holding the boy for the first time. From there, expand to describe the meaning of that memory now, such as, "Even though you have grown older, you are still our baby."
Wishes for the future are also common aspects of birthday messages for sons, and the details of a message depend on the age of the son. For example, if a son is turning 18, the birthday message might include a "good luck" statement and wishes for success as the young man embarks into a new life at college or away from home. For a younger son, the birthday wish may express a sentiment about looking forward to seeing him grow and becoming a man.
