The range is healthy — steady progress matters most. Consider a developmental check if two words haven't appeared by 3 or sentences stay very short or unclear by 4.","answer_md":"*The moment short words begin to link into little sentences is one of the most joyful leaps in your child's language journey — and it unfolds gradually.*\n\n## In short\nMost children begin joining two words together (\"more milk\", \"daddy go\") around **18–24 months**, build short three-to-four word sentences by **3 years**, and speak in fuller, grammatical sentences that a stranger can understand by **4–5 years**. There is a healthy range — what matters is steady forward progress, not a single deadline.\n\n## How sentence formation grows\n- **By 2 years** — two-word combinations and around 50+ words\n- **By 3 years** — three-to-four word sentences; uses \"I\", \"you\", simple plurals and questions\n- **By 4 years** — longer sentences, tells a short story, mostly understandable to others\n- **By 5 years** — connected, grammatical sentences with \"because\", \"and\", \"but\"\n\nSentence formation rests on earlier building blocks — listening, single words, and the back-and-forth of conversation. Children grow these skills through everyday talk, play and being read to, so rich language exposure genuinely matters.\n\n## When to look a little closer\nIt is worth a gentle developmental check if, by **age 3**, your child is not yet putting two words together, or if by **4** their sentences are very short or hard for unfamiliar people to follow. This is a reason to observe and ask — not to panic. Bilingual children are not delayed by hearing two languages.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online read.
