At two, a child can understand “don’t throw” and still lack the self-control to stop when upset. Your empathy and advance warnings are useful; add a **predictable, immediate limit on throwing**, then teach alternatives when he’s calm. This fits the [American Academy of Pediatrics’ guidance on toddler aggression](https://www.healthychildren.org/English/ages-stages/toddler/pages/Aggressive-Behavior.aspx).

Try the same sequence each time:

1. **Make the situation safe immediately.** Move the object out of reach, gently block the throw if possible, or move him away from breakables. For now, put heavy objects, appliances, and fragile items beyond his access—not just the valuable ones. Don’t ignore dangerous throwing.

2. **Use one short sentence:** “You’re mad. I won’t let you throw the cup.” Then put the cup away. Avoid explaining, questioning, or negotiating while he’s throwing.

3. **Help him settle while keeping the original limit.** Stay nearby in a safe space. Offer a hug if he wants one; don’t insist. Candy stays unavailable, and bedtime still happens. Comfort and a firm boundary can coexist. [AAP tantrum guidance](https://www.healthychildren.org/english/ages-stages/toddler/pages/temper-tantrums.aspx) and [CDC guidance on consequences](https://www.cdc.gov/parenting-toddlers/discipline-consequences/consequences.html) support intervening in unsafe behavior and avoiding giving in to tantrums.

4. **Practice a replacement when he’s calm.** Pick something simple: saying or signing “mad,” asking “help,” or coming to you. Rehearse it in play: “The block fell! I’m mad. Help, please.” During the next frustration, prompt that same response early.

5. **Notice small successes.** “You were upset and handed me the cup. That was safe.” Praise attempts, even if he’s still crying. Later, help him repair what he safely can—such as wiping a spill together. Adults handle broken glass.

Keep your transition warnings, and add small choices within the boundary: “Bedtime now. Walk or be carried?” Both parents should use roughly the same response. Clear rules, redirection, and praise are central to [AAP discipline guidance](https://www.healthychildren.org/English/family-life/family-dynamics/communication-discipline/Pages/Disciplining-Your-Child.aspx).

Time-out is an option for dangerous behavior, but it doesn’t replace teaching what to do instead. If you use it, keep it brief and predictable; the [CDC describes how](https://www.cdc.gov/parenting-toddlers/responding-to-behavior/time-out.html). You don’t need to keep adding punishments because he remains upset.

**Measure progress by safer behavior, not by whether he stops crying.** Being disappointed without throwing is a success.

Since this has lasted several weeks and involves potentially dangerous objects, it’s reasonable to discuss it with his pediatrician now—especially if it’s escalating, causing injuries, or you’re struggling to keep everyone safe. The [AAP specifically recommends seeking help in those circumstances](https://www.healthychildren.org/English/ages-stages/toddler/pages/Aggressive-Behavior.aspx).
