This study investigated parent-reported barriers and enablers to establishing sun safety practices with young children (0–4 years; N = 423) living in Australia. An online survey examined parent/child adherence to recommended sun safety practices and barriers and enablers to establishing sun safety practices. Adherence to different sun safety practices varied across age groups. Lack of child cooperation was the most commonly-endorsed barrier while child compliance was the most commonly-endorsed facilitator. Young children’s lack of cooperation with sun safety practices represents a major obstacle for parents. In conclusion, the development and testing of family-based intervention approaches to reduce child resistance and promote cooperation is warranted.
