However, it's important to remember that every child develops at their own pace. Some might start earlier, some later.
Here are some factors that can influence when a child starts using two-word sentences:
* Individual differences: Each child has their own unique developmental timeline.
* Language exposure: Children who are exposed to more language tend to develop language skills faster.
* Hearing and vision: Any issues with hearing or vision can impact language development.
* Cognitive development: The ability to understand and use language depends on cognitive abilities.
If you're concerned about your child's language development, it's always best to consult with a pediatrician or speech-language pathologist. They can assess your child's development and provide guidance if needed.
