Abstract Childhood obesity remains a critical public health concern among Hispanic families in Mexico and the United States. Healthy Change, a brief peer-led programme delivered in childcare centres, was designed to increase mothers’ awareness of child weight status and support healthier feeding practices. Embedded within a cluster randomized trial, this qualitative study examined experiences of Mexican and Mexican American mothers in the intervention arm. Four post-intervention focus groups were conducted at intervention sites (n = 25), and transcripts were analysed using inductive content analysis. Mothers reported favourable impressions, emphasizing practical advice, relatable peer facilitators, and a supportive group atmosphere. Many described initial shock or discomfort on learning that their child was overweight, followed by greater recognition of risk and intentional changes in family diet, routines, and opportunities for physical activity. Participants also identified needs for broader content, clearer communication, and some professional involvement to complement peer support. Family encouragement and involvement facilitated change, whereas competing schedules and communication gaps hindered participation. Findings suggest that peer-led programmes in childcare settings are feasible, acceptable, and capable of supporting healthier family lifestyles. Such interventions may offer a resource-efficient approach to strengthening maternal awareness and advancing early childhood obesity prevention in diverse communities.
