1. Pre-linguistic stage: This includes cooing and babbling. Babies experiment with sounds and lay the groundwork for more complex speech. 2. First words: Around one year, children start to produce single words, often simplifying complex sounds. 3. Two-word stage: By the age of two, children begin to combine words, showing an understanding of basic syntax and semantics. 4. Complex sentences: From ages three to five, children start to form more complex sentences and refine their pronunciation and grammar.
