Kate Middleton is suffering a setback in her recovery from severe pregnancy morning sickness, as her condition deteriorated on Sunday.

After spending the weekend at Kensington Palace, the Duchess of Cambridge took a turn for the worse and Prince William pulled out of an official military engagement December 9th to take care of his wife.

The Daily Telegraph reports the earliest the public could see the royal couple is Christmas day, when the family traditionally attends church at Sandringham.
