With few words and an immature impulse-control brain, hands express want, frustration, excitement or curiosity. Calm, consistent redirection and naming feelings help it fade as language grows.","answer_md":"*When your gentle one-year-old suddenly swings at a sibling or smacks your face, it can feel alarming — but at this age it is almost always communication, not aggression.*\n\n## In short\nHitting in a 1-year-old is a normal part of early development, not a sign of a behaviour problem. At this age your child has big feelings and very few words, so hands do the talking — to say *\"I want that,\" \"I'm overwhelmed,\"* or simply *\"What happens when I do this?\"* It reflects an immature brain that cannot yet pause an impulse or name a feeling. With calm, consistent guidance most of this fades as language and self-regulation grow.\n\n## Why it happens\nA one-year-old hits for reasons that all make developmental sense:\n\n- **No words yet** — hitting is how a child communicates *want, frustration or excitement* before speech arrives.\n- **Big feelings, tiny brakes** — the part of the brain that controls impulses is years from mature, so emotion spills straight into action.\n- **Cause and effect** — at this age children are little scientists; a hit gets a big reaction, which is fascinating to repeat.\n- **Tiredness, hunger or overstimulation** — a flooded nervous system reaches for the quickest release.\n- **Copying** — children mirror what they see around them, on screens or in play.\n\nNone of these means your child is unkind. They mean your child is one year old.\n\n## What helps\nStay calm and low-key — big reactions can accidentally make hitting more interesting. Gently block the hand, say a short clear phrase (*\"Gentle hands\"*), name the feeling (*\"You're cross\"*), and redirect to what they *can* do. Model gentle touch and keep routines, food and rest predictable. Consistency over weeks matters far more than any single moment.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
