This year there will be three types of badge to help you identify people.
This badge denotes that the wearer is a parent/primary caregiver and the wearer can write the name of their child/adult in the box complete with their age if wanted. Blue for boys, Red for girls. This lets you identify people likely to be going through the same stages as yourself and share information.
This badge denotes siblings or extended members of family and friends who are likely to have knowledge but are not primary carers.
These badges denote people with a professional interest. This will include presenters, researchers, attendees from care homes and educational establishments. Some of these will have additional information denoting which organisation they represent.
