One late milestone alone rarely needs action. A frontline worker should escalate to a developmental check when a child of 3.5–4 years shows no matching or grouping, when the lag travels with delays in language, play, attention or social connection, on any regression, or when a parent is persistently worried. This is early assessment, not a diagnosis.","answer_md":"*A child who isn't yet sorting toys by colour or shape is sharing useful information — and you, the frontline worker who sees them, are the first and most valuable observer.*\n\n## In short\nSorting and categorising — grouping toys by colour, shape or size — usually emerges around **2 to 3 years**, with steadier skill by 3–4 years. A single late milestone is rarely a worry on its own. Escalate to a developmental check when the child is **clearly behind peers, shows no grouping or matching by 3.5–4 years**, OR when this travels alongside delays in language, play, attention or social connection. This is a reason to assess early — never a diagnosis.\n\n## When a frontline worker should escalate\nSorting and categorisation sits within early cognitive development (ICF d1). Use these practical decision points at an Anganwadi, PHC or home visit:\n\n- **Refer for a developmental check** if a child of 3.5–4 years cannot match or group simple objects (same with same), or shows no interest in matching games even with demonstration.\n- **Refer sooner** if the gap travels with other flags — few or no words, not following simple instructions, no pretend play, poor eye contact, not pointing, or a skill that was once present being lost.\n- **Refer promptly** for any sudden regression, or if a parent reports persistent worry — parental instinct is reliable clinical information.\n- **Reassure and monitor** when sorting is the *only* lag, the child is otherwise communicating, playing and connecting well — recheck in 8–12 weeks with simple play-based practice at home.\n\nThe aim is calm, early observation, not alarm.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a screening list at the field level.
