Background <p>This study aimed to explore the knowledge, attitudes, and practices (KAP) of family members of children aged 2–6 years who snore, particularly regarding prevention, treatment, and care.</p> Methods <p>Conducted in Shenzhen from July 20 to October 20, 2024, data were collected using structured questionnaires assessing demographics and KAP scores.</p> Results <p>A total of 483 valid questionnaires were analyzed, with 318 (65.84%) completed by mothers. The majority of children (164, 33.95%) were 4 years old, and 254 (52.59%) were boys; 237 (49.07%) had snored for 6–12 months. The mean knowledge, attitude, and practice scores were 9.17 ± 2.98 (range: 0–12), 21.21 ± 1.44 (range: 5–25), and 22.34 ± 3.55 (range: 6–30), respectively. Mediation analysis found that average monthly income per person (β = 0.303, <i>P</i> = 0.005), education or training (β = -5.334, <i>P</i> = 0.020), and gender (β = -0.941, <i>P</i> = 0.012) had significant direct effects on knowledge. Meanwhile, knowledge (β = 0.23, <i>P</i> = 0.011), children’s age (β = 0.157, <i>P</i> = 0.006), education or training (β = 0.484, <i>P</i> = 0.008), duration of the child had snoring (β = -0.286, <i>P</i> = 0.007), and education level (β = 0.785, <i>P</i> = 0.014) had significant direct effects on attitude. Further, knowledge (β = 0.590, <i>P</i> = 0.011), attitude (β = 0.428, <i>P</i> = 0.008), employment status (β = -1.609, <i>P</i> = 0.031), children’s age (β = 0.22, <i>P</i> = 0.037) had significant direct effects on practice.</p> Conclusion <p>This study highlight the crucial roles of knowledge and attitude in shaping care practices, and underscore the significant influence of demographic factors (such as income, education/training, and caregiver gender) on KAP scores. These insights suggest that targeted interventions focusing on increasing awareness and providing specific education/training are essential to improve the prevention, treatment, and care practices for childhood snoring.</p>
