Kate Middleton is reportedly bed-ridden due to Hyperemesis gravidarum. The Duchess of Cambridge is currently pregnant with her second child and is suffering from a rare pregnancy complication.

Middleton has been forced to cancel a slew of royal engagements and has also moved to her mother's house for better supervision, while her husband Prince William is reportedly standing by her in the testing times.

"It's been so difficult, but she has all the people she loves around her," a royal source revealed to Boston Herald. "William's been amazing throughout all of this. He's in constant communication with the doctors. He doesn't like seeing Kate unwell and just wants her to get better so they can enjoy the rest of the pregnancy."

Prince William has been really supportive of his wife since the onset of her second pregnancy. He even stepped in for her when she was forced to cancel her solo Malta trip and took the two-day trip with aplomb and was rather happy to become the part of the country's independence celebrations.

Middleton and Prince William are already parents to one-year-old Prince George and it has further come to limelight that nanny Maria Borrallo is taking care of the toddler in the wake of Duchess' health condition.

Prince George is said to have an adventurous bone and loves to explore new things as a growing up boy, so he needs constant supervision.

"You can't let him out of your sight for a millisecond," the source tolf the daily, adding, "He's very curious - he opens anything with a door or a lid."

Meanwhile, Middleton might appear in public later this month. She may head out with Prince William on behalf of Queen Elizabeth II to greet President of Singapore, Tony Tam on 21 October, after which she may also travel to the Horse Guards Parade to attend Tam's ceremonial welcome, reported Inquisitr.

Middleton made her last public appearance at ceramic poppy art installation by ceramic artist Paul Cummins which took place at Tower of London in August.
