What was the age of pharaoh son when he died?

The age of a pharaoh's son at the time of his death can vary widely depending on which pharaoh and son is being referenced, as ancient Egyptian history spans thousands of years. For instance, Tutankhamun, who became pharaoh at a young age, died around 18 or 19 years old. Without specifying a particular pharaoh or son, it's difficult to provide a definitive answer.
