Why is something sweet put into a Hindu baby's mouth?

In Hindu culture, placing something sweet in a baby's mouth during ceremonies like the "Annaprashan" (first solid food ceremony) symbolizes the sweetness of life and the hope for a prosperous future. It is a way to introduce the child to the joys of food and life, while also invoking blessings for health, happiness, and success. Additionally, it reflects the belief in nurturing and caring for the child as they begin their journey into the world of solid foods.
