By what age should a child recognize familiar words according to language comprehension milestones?

A child should recognize familiar words by the age of 6-8 months according to language comprehension milestones. At this stage in development, infants begin to differentiate between sounds and start to associate specific words with their meanings, especially names of familiar people and objects in their environment. This recognition is not just passive; babies often respond to these familiar words with non-verbal cues, such as turning their head or reaching out towards the object or person mentioned, indicating they understand the word's significance in context. This early engagement with language sets the foundation for further language acquisition as they grow older.
