Autistic advocates emphasise the need for neurodiversity-affirming and strengths-based approaches to support services; however, little is known about broader community perspectives regarding the appropriateness of offering early support services to autistic children. This co-designed mixed-methods study employed surveys to gather insights from 253 participants in Australia and New Zealand, including autistic adults, parents, and professionals. Participants shared views on the appropriateness of early support services for autistic children. About half of participants indicated that it was appropriate to provide early support services, while the other half indicated that it depended on the nature of those support services. Reflexive thematic analysis resulted in three overarching themes which explain these views. 'They are children first, after all' emphasises the importance of preserving childhood experiences and involving children in decision-making. 'We shouldn't be aiming to fix the child' underscores the need for support services to align with neurodiversity-affirming approaches. Finally, 'Supports are beneficial' highlights the perceived positive impact that early, individualised support services can provide for autistic children. These findings predominantly signal a shift away from medicalised models towards a neurodiversity-affirming approach across participant groups.
