The Duke and Duchess of Cambridge are extremely hands on parents to their three children, Prince George, Princess Charlotte and Prince Louis.
But, the royal couple were advised against having a third child soon before they announced they were expecting Prince Louis, who was born in April 2018.
Kate and Prince William had embarked on a royal tour towards the end of 2017 throughout Poland and Germany, and Kate was gifted a baby toy while greeting members of the public in Warsaw.
