You just heard a thud and a wail. You rush in and find your toddler standing over the baby, arm still extended. Your heart races. You feel anger, fear, and guilt all at once, sometimes in the same breath.
If your older child pushes the baby, you're not dealing with a "bad kid." You're dealing with a developing brain, big emotions, and a major life transition. Research from the Merrill-Palmer Quarterly found that 68% of firstborn children display some form of aggression toward a younger sibling within the first year after birth (Volling et al., 2014). That means most families go through this.
This guide will walk you through what's happening developmentally, what to do in the moment, and how to reduce pushing over time. You're not alone, and this phase is almost always temporary.
When a two- or three-year-old pushes a baby, parents often assume the worst. But most young children aren't being cruel. They're navigating a storm of emotions with very limited tools.
According to the American Academy of Pediatrics (AAP), the prefrontal cortex, the brain region responsible for impulse control, doesn't begin maturing significantly until age 3.5 to 4, and continues developing well into adolescence. A toddler literally cannot stop themselves the way an older child can.
Here's what's often behind the push:
Understanding the why helps you respond with clarity rather than panic.
Your immediate response matters more than any long-term strategy. The goal right now is safety, not a teaching moment.
Step 1: Separate first. Calmly move the older child away from the baby. Don't grab or yank. A firm "I'm going to move you over here" is enough.
Step 2: Check the baby. Make sure the baby is safe. If you need to comfort them, do so briefly and without dramatic reactions. Overreacting in front of the older sibling can reinforce the behavior, they see that pushing gets a big response.
Step 3: Use a neutral, firm tone. Try: "I saw you push. Pushing hurts. Hands need to be gentle." Avoid "You're being mean" or "What's wrong with you?", shame increases aggression, not reduces it (Tangney & Dearing, 2002).
Step 4: Reconnect. Once everyone is calm, say: "I love you. I won't let you hurt the baby. Let's figure this out together."
Prevention isn't about hovering over your children every second. It's about managing the conditions that make pushing more likely, and building your older child's capacity for gentleness over time.
Give proactive attention. Spend even 10-15 minutes of focused, one-on-one time with your older child daily. According to ZERO TO THREE, children who receive predictable positive attention are significantly less likely to act out to get it.
Teach "gentle hands" actively. Practice on stuffed animals, on you, and then near the baby. Praise every gentle touch: "You stroked her head so softly. She liked that."
Manage the environment. Use baby gates or separate play areas when you can't supervise directly. This isn't punishment, it's teaching toddlers emotional regulation by reducing situations that overwhelm them.
Watch for triggers. Most pushing happens when the older child is tired, hungry, or has been asked to share your attention for too long. Intervene before the push, not after.
Not all pushing is equal. Here's how to tell the difference between typical sibling behavior and something that needs professional attention.
Developmentally normal (ages 2-4):
Worth monitoring more closely:
Volling (2012) found that sibling aggression typically peaks in the first year after a new baby's arrival and then gradually declines as the older child adjusts. If you're not seeing any decline after several months of consistent response, it's time to seek support.

Trust your instincts. If something feels off, it's always okay to ask.

Let's talk about you for a moment. Because when your older child pushes the baby, the guilt can be crushing.
You might think: I've ruined their life by having another child. Or: I'm failing both of them. These thoughts are incredibly common, and they're not true.
Many parents find that the early months with two children bring a grief-like feeling for the relationship they had with their firstborn. That's real, and it's worth acknowledging. But it doesn't mean you've made a mistake.
Here's what helps:
The older child isn't bad. You aren't failing. This is a hard phase in an otherwise long, evolving relationship between siblings, and helping your older child adjust to a new sibling is work that pays off over years, not days.
The pushing phase won't last forever. And what you're building underneath it, connection, security, trust — will shape how your children relate to each other for decades.
Frame the older child as the expert. "You know how to stack blocks so well — can you show her?" This gives the older sibling status and purpose rather than competition.
Praise specific kindness. Instead of a vague "good job," try: "You sat right next to your brother and used gentle hands. He was looking right at you." Specific praise reinforces the exact behavior you want to see more of.
Create older-sibling-only privileges. Staying up 15 minutes later, choosing the bedtime story, or having a special snack — these small things remind your child that being older has real advantages. Find age-appropriate ways to involve older siblings in baby care so they feel included rather than sidelined.
Some parents find that reading a personalized story about becoming a big sibling helps, because children see themselves navigating the situation successfully. Books — personalized or not — that feature sibling characters give kids a safe way to process their feelings outside the heat of the moment.
Let the baby admire the older child. As the baby grows, they'll naturally look up to their older sibling. Point it out: "Look, she's watching everything you do. She thinks you're amazing." This is powerful relationship-building that costs nothing.
The goal isn't instant love. It's safety now and gradual acceptance over time. Most siblings who pushed as toddlers grow into children who play, laugh, and genuinely enjoy each other — especially when parents respond with patience during the hard parts. For ongoing strategies as both children grow, explore approaches for managing sibling rivalry at different ages.
