First, the children of the king (legitimates and illegitimates but often legitimated) where present at Versailles. But they aged, married and had their own children. So it was all the descendants of the king (''les enfants de France'', the children of France) that where in the palace.

Yes, children were a constant and vital presence at the Palace of Versailles throughout its history as a royal residence. The "Enfants de France" (Children of France), which included the sons and daughters of the King and Queen, lived in dedicated apartments within the palace, often overseen by a "Governess of the Children of France." These royal children lived lives of immense privilege but also strict regulation, with their health and education being matters of state importance. For example, Louis XIV’s many children and grandchildren lived there, though many unfortunately died young due to the era's limited medical knowledge. Beyond the immediate royal family, the children of high-ranking courtiers also lived in or frequently visited the palace, as their parents were required to stay at court to maintain their political standing. The palace gardens and the smaller Trianon estates were often used as playgrounds for these young aristocrats. One of the most famous children associated with the later years of Versailles was the Dauphin Louis-Charles, son of Louis XVI and Marie Antoinette, who lived there until the royal family was forced to leave for Paris during the French Revolution in 1789.
