Having to leave a child's bedside when they're being cared for in hospital can be a huge wrench, especially at this time of year.

To help reduce the separation anxiety, a third of neonatal units in the UK have signed up to an app that helps parents stay in touch with their premature babies 24 hours a day.

Doctors and nurses can send photos and video updates to parents when they can't be with their baby in hospital and so far, about 5,000 families have used the service.
