Mercure has unveiled a series of spa treatments for expectant parents in an effort to reap the benefits of the 'babymoon' trend, where couples treat themselves before the arrival of their newborn.

The babymoon menu is specifically designed to be safe for expectant mothers and their unborn baby and treatments target concerns such as stretch marks, skin tone, tired and swollen legs.

Fathers are not excluded from the spa menu with the 85-minute Total Body Wellness including a body polish, massage and sauna mask.

Mercure says even the Duke and Duchess of Cambridge have jumped on the babymoon trend, taking relaxing getaways before the arrival of their child in July.

Treatments will be available at Spa Natural Fitness at Mercure spa hotels across the UK.
