Newborn — 12 months

The age of discovery · sensory exploration · first connections

Motor

Lifts head

Between 1–2 months, baby starts briefly lifting the head during tummy time, strengthening the neck.

Motor

Grasp reflex

Newborns automatically grip whatever is placed in the palm — this reflex evolves into intentional reach by 3–4 months.

Motor

Rolls over

Between 4–6 months, most learn to roll from tummy to back and back again — a big motor leap.

Motor

Eyes follow faces and objects within weeks. By 3 months, they track side-to-side across the full field of view.

Cognitive

Object permanence

Around 8–9 months, baby begins to understand that objects still exist when hidden — the foundation of logical thinking.

Language

Early babbling

Between 1–3 months, soft vowel sounds appear — the very first 'conversations' with caregivers.

Language

Repeated syllables

By 6 months, strings like 'ba-ba' and 'ma-ma' emerge — direct precursors to first words.
