Verified step by step guidance

1. Understand that the question is about language development milestones in children, specifically the transition from simple to more complex sentence production.
2. Recall that in developmental psychology, language acquisition follows a general timeline where children start with single words and then move to simple two-word phrases.
3. Recognize that the transition to more complex sentences typically occurs when children begin combining multiple words with grammatical structure, which usually happens around 2 to 3 years of age.
4. Note that options like 'around 6 to 8 years old' or 'during adolescence' are later stages where language skills become more refined but the initial transition to complex sentences happens earlier.
5. Conclude that the correct developmental period for this transition is around 2 to 3 years old, based on typical language acquisition patterns observed in developmental psychology.
