These are gentle guides, not deadlines, and a few months' variation is normal. Block stacking reflects pincer grasp, hand-eye coordination and attention developing together.","answer_md":"*Those wobbly little towers your toddler builds are tiny milestones — each block stacked is a quiet win for growing hands and a focused mind.*\n\n## In short\nMost children begin stacking around their first birthday: a tower of **2 blocks by about 15 months**, **3–4 blocks by 18 months**, **6 blocks by around 2 years**, and **8–10 blocks by 3 years**. These are gentle guides, not deadlines — children vary, and a few months either side is usually nothing to worry about.\n\n## The science\nBlock stacking is a beautiful blend of skills coming together. It needs a steady **pincer grasp**, good **hand-eye coordination**, the **wrist control** to release a block precisely, and the **attention** to keep going. That's why occupational therapists watch it closely — a tower quietly tells us how a child's fine-motor and visual-perceptual systems are maturing. As the tower grows taller with age, so does the child's planning and patience.\n\n## When to keep an eye out\nGentle flags worth a developmental check include: not picking up small objects with thumb and finger by around 12 months, no attempt to stack two blocks by 18 months, or consistently using only one hand while the other stays tightly fisted. Pair any motor concern with how your child plays, points and communicates — the whole picture matters more than one skill.\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 the care of a qualified clinician — never from a website or a single milestone.
