Which of the following is a common developmental milestone for children aged 2-3 years?

Children aged 2-3 years typically begin to use simple sentences as part of their language development. At this stage, they are expanding their vocabulary and starting to combine words into basic phrases, which is crucial for effective communication. This milestone marks a significant step in their cognitive and linguistic growth, as they move from single words to more structured language.

Engaging in conversations, even with simple sentences, allows them to express their needs, thoughts, and feelings more clearly. It also aids in social interactions and learning from their environment, as they start to understand and use language as a tool for communication.

The other options describe skills that develop either later or require a level of proficiency not typically seen in children within this age group. For instance, reading simple books usually develops after children have a stronger grasp of language and literacy skills, while writing their names and jumping rope are milestones that emerge later in their development.
