Based on the framework of timing theory， this study explores the caregiving experiences of caregivers for children with severe burns at different disease stages， providing a basis for constructing staged intervention plans and establishing a diversified support system.

A qualitative research method was employed， using purposive sampling combined with maximum differentiation sampling strategy to select 18 caregivers of children with severe burns who were treated at Department of Burns and Cutaneous Surgery， Burn Center of PLA， Xijing Hospital, Air Force Medical Univercity from January 2024 to December 2024 as study subjects. Guided by the timing theory， face-to-face semi-structured interviews were conducted at different stages， and data were collected and analyzed using content analysis to extract themes.

Three themes were identified based on burn staging， comprising 9 sub-themes. (1) Shock stage： self-blame/guilt and urgent treatment needs； (2) Treatment stage： shift in life priorities， anxiety due to lack of knowledge， heavy financial burden， demanding caregiving tasks， and desire for social assistance； (3) Rehabilitation stage： increased concerns about the child's future and the need for rehabilitation care.

Healthcare providers， family members， and social organizations should pay attention to the dynamic caregiving experiences and changing needs of caregivers for children with severe burns at different disease stages， providing comprehensive， meticulous physical and psychological care and professional guidance. While improving the treatment success rate of pediatric burn patients， it is essential to address the needs of their caregivers by establishing a comprehensive support system to alleviate psychological burdens. This approach will better facilitate the treatment and rehabilitation process for severe burn patients， ultimately enhancing their quality of life.
