The range is wide and gradual; steady progress matters more than an exact date. A gentle check is wise if no two-word combinations appear by 24 months or speech stays single-word by age 3.","answer_md":"*The leap from single words to little sentences is one of the most joyful chapters of toddlerhood — and it unfolds gradually, not overnight.*\n\n## In short\nMost children begin joining two words together (\"more milk\", \"daddy go\") around **18–24 months**, and by **30–36 months** they string together simple three- to four-word sentences with growing grammar. There is a wide, healthy range — what matters is steady forward movement, not hitting a date exactly.\n\n## How sentence complexity grows\n- **12–18 months** — single words, gestures, and lots of pointing to share meaning.\n- **18–24 months** — two-word combinations appear (\"want ball\", \"mama up\"). Vocabulary often jumps quickly here.\n- **24–30 months** — short phrases, early use of \"my\", \"no\", plurals and simple questions.\n- **30–36 months** — three- to four-word sentences, longer ideas joined together, and speech a familiar adult can mostly understand.\n\nChildren growing up with two languages may mix them and may seem a little slower in one — this is normal and not a delay. Comprehension (understanding what you say) usually runs ahead of what they can say themselves.\n\n## When to look a little closer\nIf by **24 months** your child isn't combining any two words, or by **3 years** still speaks mostly in single words, a gentle developmental check is wise — most often to reassure, and to start early support if helpful.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from a web page or a worry alone.
