At what age should a child stop babbling, which is considered a developmental warning sign?

The appropriate age for a child to stop babbling without any further speech development is considered to be around 10 to 11 months. Babbling is an important milestone in a child's language development, as it indicates the early stages of speech production and is a precursor to more complex language skills. By the age of 10 to 11 months, children typically begin to progress from simple babbling toward the use of more intentional vocalizations and the emergence of first words. If a child does not show this progression by that age, it may be a developmental warning sign, suggesting the need for further evaluation to ensure they are on the right track with their communication development.
