The Duchess of Cambridge is due to have her third child on the feast day of St George on Monday, April 23. A royal source said: “There's no certainty with due dates of course but the Duchess is working off a date around St George’s Day and it would be a lovely patriotic coincidence if he or she were born then. “The one thing that is certain though, if it’s a boy he won’t be called George! Prince George has already taken that one. “Or if she’s very late, as she was with George’s birth, she could even make it a very special wedding anniversary present to William, as they celebrate seven years of marriage on the 29th April.”

The odds are in favour of the future royal being a girl which is priced at 4/5. Ladbroke’s Jessica Bridge said: "Punters have been convinced Kate is expecting another girl, but her head-to-toe blue outfits could start to change public opinion, and the odds, very quickly." A spokesman for the couple declined to comment. The due date was confirmed by Kensington Palace in October last year.

Parents usually wait until about 12 weeks into the pregnancy - the third trimester - until they announce the news. News a new royal baby was on the way was revealed on September 4, 2017. The early announcement came due to Kate’s tendency to hyperemesis gravidarum - severe morning sickness. Hyperemesis gravidarum morning sickness is usually worst between eight and 12 weeks.
