An excited Kate reveals: The baby won't stop kicking!

The smile on Kate’s face says it all as she and her baby anticipate its exciting arrival.

With just five weeks to go before her due date, Kate Middleton has excitedly told friends that she is carrying one very active royal heir! Woman’s Day can reveal the duchess’s baby has plenty of energy, with bub giving mum frequent reminders about its imminent arrival.

“The baby is kicking a lot,” says a member of Kate and Wills’ inner circle. “Kate’s not sleeping very well.”Sleep aside, it’s clear these intimate mum and baby moments are bringing Kate great joy, and she’s unable to wipe the smile off her face.

A friend of the duchess says it’s all due to striking the perfect balance between work and staying calm as her baby’s birth approaches. “Kate is calling it D-day,” another close friend tells. “She’s so happy and positive right now, she doesn’t seem worried at all … she’s slowed right down.” With the eyes of the world on her as she approaches the birth of the third in line to the British throne, Kate’s found her own way of coping with any stress. She’s doing gentle exercise, reading baby books and planning an intimate baby shower.

“She likes to swim in the [Kensington] palace pool,” UK-based royal correspondent Robert Jobson tells Now magazine. “She gets there whenever she can for some private relaxation. She’s not at all stressed – she just has the usual worries of an expectant mother.”
