She’s already a mother to three adorable royal babies, and while nothing has been confirmed, that doesn’t mean the odds Kate Middleton announces a fourth pregnancy before the year ends aren’t high.

Royal fans have been in a frenzy since earlier this year that the Duchess of Cambridge could be planning to have one more child with Prince William after she made a comment during a royal outing that she was feeling “broody.” Since then, other sources have come forward to claim that Middleton, 37, does want to have another baby, despite her history of contracting hyperemesis gravidarum, and several moments with the Duchess have been analyzed to depict whether or not she may already be pregnant. However, despite no confirmations from the royal family about a pregnancy, and no other outward signs from Middleton herself that suggest she is having a child, royal betting odds are still at an all-time low over the possibility she may decide to have one more kid.

Most recently, bookmakers Coral slashed the odds again that Middleton would announce a pregnancy before 2019 comes to an end, stating that the new odds are 1 /2.

“On Prince George’s sixth birthday, there’s been plenty of talk about whether William and Kate will add to their family,” spokesman Harry Aitkenhead told Express UK. “We think a fourth baby is very likely and make it odds on that the Duchess of Cambridge announces she is expecting again by the end of this year.”

However, despite the odds, Middleton could still surprise everyone by not announcing a fourth baby at all, as there are reasons to believe she may stop now that she has had three children.

It has been noted during the rare outings with Prince Louis that Middleton apparently dotes on her youngest child in a way that indicates she may know he is the last baby she will have, and there have also been indications that she may be thinking about her age and whether another pregnancy is worth it because of that. Though she is likely perfectly capable of conceiving another child, pregnancy after age 35 is considered geriatric, which implies higher risk factors before birth.

Of course, that also may not scare Middleton away from the idea of a fourth pregnancy either, as her sister-in-law, Meghan Markle, was 37 when she welcomed her first child, Archie Harrison, this past May.
