Bizarre cravings are a part of many pregnancies and it seems Kate Middleton is no exception - she has been combatting her chronic morning sickness by munching her way through lavender biscuits made by Charles's firm Duchy Originals.

The lavender-infused shortbread biscuits were recommended to her by her step mother-in-law Camilla, the Duchess of Cornwall, according to the Sun, which says that Charles and Camilla have been sending Kate boxes of the unusual biscuits, sold by London store Fortnum and Mason.

A few drops of lavender in a bath is often thought to combat morning sickness.
