What age do children begin speaking in sentences?

There's no single answer to this question because language development varies greatly from child to child. However, here's a general timeline:

* Around 18 months: Most children start putting two words together, like "want milk" or "more juice".

* By 2 years old: Children typically begin to speak in short, simple sentences, often with just a few words.

* By 3 years old: Children's sentences become longer and more complex, using prepositions and more verbs. They might start asking "why" questions.

* By 4 years old: Children can usually speak in complete sentences and understand more complex grammar.

Factors that influence language development:

* Hearing: Children who are regularly exposed to spoken language develop language skills faster.

* Genetics: Family history of language development can play a role.

* Environment: A stimulating environment with opportunities to interact and communicate encourages language growth.

* Cognitive development: Language skills are intertwined with cognitive abilities.

* Social interaction: Children learn language by interacting with others.

If you have concerns about your child's language development, talk to your pediatrician. They can assess your child's progress and provide guidance if needed.
