With ‘Heart Friends’, de Hartstichting (Dutch Heart Foundation) offers support to children living with a heart disease and their parents. Heart Friends has developed The TikkieRing to help young children process their experiences and more easily share their stories with their family, friends, and other children. This TikkieRing with Tikkies (charms) is a reward for their courage, strength, and perseverance. With our support, ‘Heart Friends’ can contribute to positively changing their lives.
