What is one of the first signs of a potential developmental disability in infants?

Lack of babbling is one of the first signs that may indicate a potential developmental disability in infants. Babbling is an important milestone in early language development and typically starts around 4 to 6 months of age. If an infant is not babbling by this time, it can suggest delayed speech development and may warrant further evaluation for potential developmental issues.

In contrast, excessive weight gain may not be directly indicative of a developmental disability and could be influenced by a variety of factors, including genetics and nutrition. Continuous laughter is generally a positive sign of social engagement and emotional development, and rapid crawling is often celebrated as a sign of physical development rather than a concern. Therefore, the absence of babbling stands out as a critical early indicator that specialists look for when assessing an infant’s developmental progress.
