Try this first
Block the hit calmly — catch their wrist or step back. Safety first, lecture never.
Check on whoever got hurt first. Attention lands where it’s needed, not on the hitter.
Once settled, name what they couldn’t: “you were cross because…” Give them the words for next time.
Why this works
Stop the behaviour calmly and physically: "Hitting hurts. I won't let you hit." Get down to their level and name the feeling: "You're so angry that…" Then offer the alternative in the same breath — use your words, stomp your feet, squeeze a pillow. Move them away from the target if needed. Right now, your job is to be the prefrontal cortex they don't yet have. Watch for high-risk windows (tired, hungry, overstimulated, mid-transition) and step in early. Be consistent — every single time, the same calm response. And catch the wins out loud: "You wanted that toy and you used your words!" If hitting is intense, frequent, or lasting more than a few weeks despite your responses, it's worth a chat with your GP or health visitor.
Many toddler behaviour spikes come from hunger, tiredness, transitions, or a mismatch between big feelings and limited language. The goal is regulation first, teaching second.
When should I worry about hitting or aggression?
If this pattern feels intense, persistent, or starts affecting sleep, safety, nursery, or family routines, it’s worth speaking to a professional. Your health visitor or GP can discuss your concerns and refer you to specialist support if needed. The NSPCC helpline (0808 800 5000) also offers free, confidential advice on any child behaviour concern.

Meltdown
Start with calm regulation, then move to a simple activity that helps the moment settle.
Use this when hitting, pushing, or throwing has started and you need to respond steadily in the next 10 seconds.
When to step back
If your child is in danger or another child is being hurt, prioritise physical safety over emotional coaching. Separate first.
What success looks like
A moment where your child pauses before hitting, or accepts the alternative you offer. Progress is measured in fewer incidents over weeks, not perfection today.
What to try first
Block the hit calmly, get to their level, and name what you see: ‘You are angry. I will not let you hit.’
Hitting feels alarming the first few times you see it, but by 17 months most toddlers will hit at some point — it's normal developmental territory, not a sign something is wrong. The part of the brain that handles impulse control (the prefrontal cortex) is one of the last to mature, and real self-control doesn't start coming online until around 3½ to 4 years old. Until then, when feelings are bigger than words, the body acts first. Excitement and frustration travel similar neural pathways, which is why even happy or overstimulated toddlers hit. The NSPCC frames this well: hitting is communication, just not the kind we'd choose. There's also an expectation gap — a 2½-year-old can repeat "no hitting" and still hit ten seconds later, because they know the rule but cannot yet stop themselves from acting on impulse.
What should I avoid during hitting or aggression?
Don't hit back or use any form of physical punishment — it models the very thing you're trying to stop, and the AAP is clear that it predicts more aggression over time. Avoid long lectures in the moment ("We don't hit because…") — a dysregulated brain genuinely can't process them. Don't label your child as "mean" or "bad" — it shames them without teaching the skill. Don't ignore it hoping it'll pass on its own. And don't expect a sincere apology from a young toddler — they're not yet developmentally ready to mean it.
Most families see fewer incidents within 2–3 weeks of a consistent response. It’s normal for the behaviour to briefly intensify before improving — this is a sign your child is testing the new boundary, not that it isn’t working.
