Language acquisition in multilingual children typically progresses through several stages, influenced by factors such as age, exposure to different languages, and individual learning styles.

1. Prelinguistic Stage: In this stage, infants are developing the foundational skills for language, such as babbling and making sounds. They are also learning to differentiate between the languages they are exposed to.

2. One-Word or Holophrastic Stage: Children begin to use single words to communicate basic needs and ideas. For example, a child might say "milk" to indicate they want a drink.

3. Two-Word Stage: At this stage, children start combining words to form simple phrases, such as "more juice" or "big dog."

4. Telegraphic Speech Stage: Children begin to use short, simple sentences that focus on conveying essential information. For instance, a child might say "me go park" to express a desire to go to the park.

5. Complex Sentences Stage: As children's language skills continue to develop, they start using more complex sentence structures and expressing more nuanced ideas and emotions.

It's important to note that the progression through these stages can vary widely among multilingual children, depending on their exposure to different languages and individual developmental differences.
