However, during all her pregnancies, Kate Middleton suffered from hyperemesis gravidarum, an extreme form of morning sickness. This meant that she and her husband had to announce the news at a different time than they had planned. Indeed, the Duchess had had to cancel engagements when pregnant with Louis, including taking George to his new school.
Meanwhile, members of the royal family and the British government offered their congratulations to Kate and William. Prince Harry, during a trip to the English city of Manchester, said that he was “very, very happy” to hear about the new addition. And British Prime Minister Theresa May tweeted out her best wishes, adding that the announcement was “fantastic news.”
And when Prince Louis was born on April 23, 2018, Kensington Palace released the news on social media. The Twitter post read, “Her Royal Highness the Duchess of Cambridge was safely delivered of a son… The baby weighs 8lbs 7oz. [William] was present for the birth. [Kate] and her child are both doing well.”
