“Royal baby” is a term that became popular when it was revealed that Catherine, Duchess of Cambridge was pregnant with her first child in 2012. Speculation immediately began as to the sex of the baby and what name would be chosen for him or her. Naturally, the media immediately found a term to use for Kate Middleton’s offspring, and thus royal baby was born. As the birth became inevitable, the term “royal baby” was a trending topic on social media until, on July 22, 2013, Prince George was born. The saying was once again popular with the birth of the Duke and Duchess of Cambridge’s second child, Princess Charlotte, in 2015.
