Which behavior is indicative of normal growth and development in a two-year-old child?

The emergence of two to three-word sentences in a two-year-old child is a strong indicator of normal language development. At this age, it is typical for toddlers to start combining words to express more complex ideas and needs, reflecting their growing cognitive and social skills. This developmental milestone signifies progress in both their language acquisition and social interaction abilities, as they learn to communicate desires, emotions, and observations more effectively to those around them.

In contrast, while some children may begin to use a fork or complete puzzles with assistance, these skills can vary significantly among two-year-olds and might not be consistent indicators of their overall development. Writing their name is generally not a milestone until later in preschool years, as fine motor skills and literacy skills typically develop after basic language skills. Thus, the ability to speak in sentences at the age of two is a clear sign of typical growth and development in a child.
