Days before Duchess Kate's due date, she has been given a strict warning

As the much awaited due date approaches, experts suggest the Duchess take more care of herself.

The Duchess of Cambridge, Kate Middleton, has been advised to take complete rest during her maternity rest and keep her entire focus on her current pregnancy.

According to All Cute All The Time, Middleton's advisor Clare Livingstone revealed that third-time mothers have their attention divided, so they must be aware of 'any factors in the upcoming days.'

"She’s probably much more tired so it's the importance of rest, nutrition, hydration, monitoring baby's movements and reporting any noticeable difference with that," the source quoted Livingstone as stating.

The Duchess of Cambridge has been specially instructed to 'keep an attentive eye' on her baby's movements. If the baby's activity increases, Middleton would know that the time for the baby's arrival has neared.

As the Duchess' due date is nearing, it is important that she can alert her team in time so that they can begin the delivery process, the source suggested.

Middleton was earlier advised to take her maternity leave way before her April due date. But the Duchess kept herself busy right until her last day before taking her leave. Only a couple of days after that, she further made an appearance in another event as well.

The Duchess has proved herself to be one of hardest working members of the Royal Family. She kept herself busy right until the last possible day, working non-stop.

From attending A-list evening balls to other charity events as well as international travel to wedding planning, Middleton seemed to be everywhere.

In her earlier pregnancies as well, the Duchess kept herself busy but she did not have the added pressure of her two other children, the source suggested.
