How many words should an infant understand by the age of 1 year?

At around the age of 1 year, infants typically understand a few words as they begin to develop their language skills. Understanding of 3-5 words is in alignment with developmental milestones established in pediatric health. By this age, infants may start to recognize and respond to simple commands or familiar words such as "mama," "dada," or the names of familiar objects.

Recognizing this level of comprehension is important for caregivers and healthcare professionals, as it helps to track a child's language development and overall cognitive growth. Following this typical trajectory aids in identifying any potential delays or concerns early on in the child’s development, allowing for timely intervention if needed.
