Convincing conspiracy theories abound that Meghan Markle has already given birth.

An ambulance was seen near Meghan and Harry’s Windsor mansion last week, and Harry has announced a trip to the Netherlands next week, fuelling rumours Baby Sussex has arrived healthy, so Harry can head overseas for two days, no problem – Meghan’s mum Doria Ragland is on hand to help, along with a full staff, after all.

But a strong sign that Meghan is yet to give birth comes in the form of an innocuous seeming Instagram comment the @SussexRoyal account left on the @KensingtonRoyal account, AKA William and Kate’s account, overnight.

Wishing Princess Charlotte a happy fourth birthday, Meghan and Harry wrote:

“Happy Birthday Charlotte! Lots of love, H and M xo”

If Baby Sussex had arrived, wouldn’t they instead sign-off “the Sussex family” or “the Sussexes” or “H, M and BS [Baby Sussex]”?

Nobody puts Baby Sussex in the corner.

Just an instinct.

Meghan’s due date was Sunday April 28. The couple previously said they would spend a few days celebrating “privately” before announcing the news.
