The Daily Mail reports the duchess could now be induced this week at St Mary's Hospital in Paddington.

While Kensington Palace says it never confirmed a due date, it is widely believed she was due to give birth on Saturday, with some reports suggesting her due date was as early as last Thursday (23 April).

A source told the Daily Telegraph, "The doctors don't normally wait for more than a week.

"They will probably already have been in touch with Kate, and talked about which day which suit her best to go in and be induced if the baby doesn't arrive in the next couple of days."

Kate Middleton Announces Her Due Date--When Is It?

William and Kate's first child, Prince George, was born three days late at the hospital's private Lindo Wing back in July 2013.

The royal couple has not revealed what names they favour, but, according to the Inquisitr, bets currently favour Alice for a girl and James for a boy.

Kate's mum Carole is already in London awaiting the arrival of her second grandchild. She was spotted looking "happy and smiley" as she headed to the Richard Ward hair salon on Friday.
