On its own it is not a sign of autism. What matters is the wider picture — communication, connection and varied play. A relaxed developmental check brings clarity if you'd like reassurance.","answer_md":"*Your two-year-old solemnly arranges every car in a perfect row — and you wonder what's going on in that busy little mind.*\n\n## In short\nLining up toys is a **very common, usually completely typical** part of how two-year-olds play and learn. At this age children are discovering order, patterns, cause-and-effect and how things relate to each other — and lining things up is one satisfying way to explore that. On its own it is **not a sign of autism or any concern**. What matters is the bigger picture: how your child communicates, connects and plays *alongside* the lining-up.\n\n## Why toddlers line things up\nAround age two, the thinking brain is busy sorting the world into categories — same and different, big and small, this colour next to that one. Lining up toys is a hands-on way to practise that. Children also love the feeling of control and repetition; an orderly row is predictable and pleasing, much like stacking blocks or filling and emptying a box over and over.\n\nIt becomes part of healthy play when your child:\n- Lines things up **and** also plays with the toys in other ways (pushing the cars, feeding the dolls)\n- Looks up to share the moment with you — pointing, smiling, showing\n- Moves on happily when play changes or a toy is gently moved\n- Is also babbling, using words, gesturing and responding to their name\n\n## When it's worth a gentle check\nLining up is only a flag when it sits within a wider pattern over time — for example, if it is the *only* way your child plays, comes with intense distress when a row is disturbed, and appears alongside little eye contact, few words or gestures, or not responding to their name. These are reasons for a relaxed developmental check, not alarm. Trust your instinct: a [simple screen](/ask/what-is-the-abilityscore-and-how-is-it-calculated) brings clarity either way.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
