From the dailymail:
The Duchess of Cambridge was last night resting at the London home she shares with Prince William after her release from hospital yesterday morning.
Kate, who was admitted to hospital on Monday suffering from acute morning sickness, returned to Nottingham Cottage in the grounds of Kensington Palace and cancelled upcoming engagements after doctors told her to rest.
After spending three nights in hospital with acute morning sickness, no doubt all she wanted to do was go home and curl up quietly on the sofa – but you’d never have known it as she left the King Edward VII Hospital in London yesterday.
Instead, the ever professional Kate treated wellwishers to a beaming smile.
Looking perhaps a little tired and pale, but as immaculate as ever, pregnant Kate told the waiting crowds: ‘I’m feeling much better, thank you.’
Meanwhile Prince Charles revealed his delight as he spoke for the first time about his son’s happy news. ‘I’m thrilled, marvellous,’ he said.
