Meghan Markle Baby Watch on High Alert

The baby's due any day, making royal watchers nervous wrecks.

The Meghan Markle baby watch has hit a fever pitch.

Royal watchers are nervous wrecks, searching for any sign that the baby is on the way or already here. 

Dad-to-be Prince Harry made a surprise appearance at the London Marathon finish line on Sunday, which some people took as a sign that the delivery wasn't imminent. After all, he'd otherwise be by Meghan's side. 

Reports say the Duchess of Sussex will deliver the baby at Frogmore Cottage, where the couple lives. A helicopter will reportedly be waiting nearby in case she needs to go to the hospital. 

Meghan and Harry have made it known that the delivery of their first child will be very private — they will not be showing the baby off to the world hours after delivery as Prince William and Kate Middleton did. 

Signs have been put up near their home stating that drones are prohibited in the area, serving as words of caution to keep the paparazzi away.
