Children with neurodevelopmental disabilities often struggle in multiple areas, including language development. While standard speech therapy mainly focuses on understanding and producing words, these children may also have difficulties with the social and communicative skills needed for language. The parent-child relationship is especially important for helping kids develop in their early years.\n\nThis clinical trial aims to find out if an intervention focused on early social and communication skills, and involving parents, can help children with neurodevelopmental disabilities. The study includes children aged 6 months to 5 years.
