# Cognitive milestones for frontline routine visits

Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

During routine visits, frontline workers should check age-based cognitive markers — object permanence, cause-and-effect play, pointing to share, following instructions, pretend play and memory — alongside parent concern. These are watch-and-monitor checks; any persistent gap or lost skill is a reason to route the child for a developmental check, never a diagnosis.

*Cognition rarely announces itself — it shows in whether a baby searches for a hidden toy, points to share a discovery, or solves a small problem on their own. The frontline worker is often the first to notice the pattern.*

## In short
During routine home and PHC visits, check whether a child's **thinking, attention, memory and problem-solving** are tracking with age — using simple, observable markers and the parent's report. These are watch-and-monitor checks, not diagnoses: any persistent gap or loss of a skill is a reason to route the child for a developmental check, not to wait.

## Cognitive markers to check, by age
**By 6 months** — follows moving objects with eyes; brings objects to mouth to explore; shows interest in faces.

**By 9–12 months** — looks for a partly hidden toy (early object permanence); bangs or shakes objects to see what happens; responds to own name; copies simple gestures like waving.

**By 18 months** — points to show you something interesting; explores cause-and-effect toys; begins simple pretend (feeding a doll); follows a one-step instruction.

**By 2 years** — sorts shapes or colours; completes simple puzzles; follows two-step instructions; remembers where things are kept.

**By 3 years** — engages in pretend play; understands "one" vs "many"; matches and groups objects; turns book pages and looks at pictures with meaning.

**Always act on** any **loss of a skill** the child once had, or strong, repeated parental concern — these warrant prompt onward referral at any age.

## The science
These map to ICF **mental functions (b1)** — attention, memory, thought and higher cognitive function. A single missed marker is not a diagnosis; a *pattern* across visits, or regression, is the signal to route onward. Pair every cognitive check with a [hearing and vision](/cognitive) screen, as sensory gaps can mimic cognitive delay.

## The Pinnacle way
A 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 — your field observation starts that pathway, it does not replace it. Onward support may include [cognitive and play-based therapy](/cognitive-therapy) tailored to the child. Backed by 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres.

## Trusted sources
Aligned with the WHO ICF framework for mental functions (b1), and CDC and AAP developmental-milestone guidance for routine surveillance.
