Here's a general timeline:
* 12-18 months: Babies begin to understand simple words and use single words like "mama," "dada," or "ball."
* 18-24 months: Children start combining words into simple phrases ("want juice") and their vocabulary expands rapidly.
* 2-3 years: Children develop longer phrases, start using plurals and possessives, and understand simple questions.
* 3-5 years: Children become more fluent, using complete sentences, telling stories, and participating in conversations.
* 5-7 years: Language skills continue to develop, including more complex grammar, vocabulary, and the ability to understand nuances of language.
Factors that influence fluency:
* Individual differences: Some children are naturally "early talkers" while others develop language at a slower pace.
* Environment: Exposure to rich language, interactions with adults, and opportunities to use language all contribute to fluency.
* Hearing: Hearing impairments can affect language development.
* Cognitive abilities: Cognitive abilities like memory and attention play a role in language acquisition.
If you have concerns about a child's language development, it's important to consult with a pediatrician or speech-language pathologist. Early intervention can be beneficial if needed.
