The firstborn is often seen as a symbol of hope, pride, and responsibility in family life. From birth, they are the first to be nurtured, cared for, and taught by their parents and siblings.

In conclusion, the firstborn plays a significant role in family life, providing stability, leadership, and support to their family and friends.
