Support Us Volunteering How much time do I have? Child Dynamix has volunteers working across the charity supporting service delivery, raising funds and expanding the capacity of their teams and we recognises that volunteers are key to the success of our work. Whether the time you have to donate is 30 minutes, 30 hours, 30 days, or more! Child Dynamix recognises the contribution of our volunteers who work with us to make our communities a better place. If you have some time that you wish to donate and are interested in volunteering to help us continue our work with children, young people and families in Hull click here.
