Toddler Hitting
The short answer
Hitting is a very normal part of toddler development and does not mean your child is aggressive or that you are doing something wrong. Toddlers hit because their brains are still developing impulse control and they lack the language to express big feelings. With consistent, calm guidance, most children learn better ways to cope by age 3-4.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
9-14 months
Babies at this age often swing their arms and make contact with faces or bodies without any intent to hurt. They are experimenting with cause and effect - "I swing my arm, and something interesting happens!" Slapping or smacking your face may even be accompanied by giggles. A calm, neutral response helps them learn without reinforcing the behavior through big reactions.
14-24 months
This is when hitting most often becomes intentional, driven by frustration, wanting a toy, being told "no," or simply feeling overwhelmed. The prefrontal cortex - the part of the brain responsible for impulse control - is still very immature. Your toddler genuinely cannot stop themselves in the moment, even if they "know" hitting is wrong. Consistent responses like gently catching their hand and saying "I won't let you hit. Hitting hurts" are most effective.
2-3 years
Hitting may continue but should start decreasing as language and emotional regulation develop. Two-year-olds are often caught between knowing the rule and being able to follow it. Keep teaching feeling words ("You're mad! You wanted that toy"), offer alternatives ("You can stomp your feet"), and stay calm. Progress may be slow but it is happening, even when it doesn't feel like it.
3-4 years
Most children hit much less frequently by age 3-4 as language and self-regulation improve. If hitting is still frequent, intense, or escalating at this age, it is a good idea to talk with your pediatrician. They can help determine if there are underlying factors like sensory needs, anxiety, or communication difficulties that would benefit from support.
What Should You Do?
When to take action
- Your toddler hits when frustrated, overwhelmed, or overtired - these are the most common triggers
- Your baby smacks your face during play without seeming to understand it hurts
- Hitting happens occasionally but your child also shows affection, empathy, and is gradually improving with consistent guidance
- Your toddler is between 1-3 years old and the behavior is slowly decreasing over time
- Hitting is very frequent (many times daily) and is not improving despite weeks of consistent, calm responses
- Your child seems to hit without any identifiable trigger, not related to frustration, excitement, or social conflicts
- Your child is over 3 and still hitting regularly at home or at school or daycare
- Hitting is accompanied by other intense behaviors like severe tantrums, property destruction, or extreme difficulty with transitions
- Your child hurts themselves intentionally - hitting their own head, biting themselves, or scratching - especially if it is escalating
- Your child has injured another child or adult seriously (bruising, breaking skin) and does not seem distressed about it
- There is a sudden increase in aggressive behavior after a major life change, trauma, or alongside regression in other skills

Related Behavior Concerns
Aggressive Play vs Normal Play
Rough-and-tumble play — wrestling, chasing, play-fighting, and superhero battles — is a normal and important part of child development, particularly for toddlers and preschoolers. It helps children develop physical coordination, social skills, self-regulation, and an understanding of boundaries. The key distinction between normal rough play and concerning aggression is whether both children are having fun, there is turn-taking in roles, and no one is intentionally trying to hurt the other.
My Toddler Is Aggressive Toward Pets
Toddlers being rough with pets is extremely common and almost never reflects true aggression or cruelty. Young children lack the motor control to be consistently gentle and do not yet understand that animals feel pain the way they do. With patient, consistent teaching about gentle touch and close supervision, most toddlers learn to interact safely with pets by age 3-4.
My Baby Doesn't Seem Attached to Anyone
By 7-9 months, most babies show clear preferences for their primary caregivers and some wariness of unfamiliar people. If your baby seems equally comfortable with everyone and shows no distress when separated from caregivers, it may simply reflect an easy-going temperament. However, if combined with other social differences, it can occasionally warrant further discussion with your pediatrician.
Attachment Parenting Burnout
Attachment parenting principles (responsive feeding, babywearing, co-sleeping) can foster strong parent-child bonds, but the all-encompassing nature of the approach can lead to parental exhaustion and burnout, particularly for the primary caregiver. Research shows that secure attachment comes from being consistently responsive to your child — it does not require 24/7 physical proximity, exclusive breastfeeding, or co-sleeping. A burned-out, resentful parent is less able to provide the emotional responsiveness that is at the true heart of secure attachment.
Attention Span Expectations by Age
Young children naturally have very short attention spans, and this is completely normal. A general guideline is roughly 2-3 minutes of sustained focus per year of age, so a 2-year-old might focus for 4-6 minutes on a single activity. Attention span develops gradually over childhood and is strongly influenced by interest level, environment, and temperament.
Baby Arching Back and Crying During Feeding
A baby who arches their back and cries during feeding is often showing signs of discomfort. The most common cause is gastroesophageal reflux (GER) - stomach acid flowing back into the esophagus causes a burning sensation, and the baby arches to try to relieve it. Other causes include an improper latch (breastfeeding), a bottle nipple with too fast or too slow a flow, ear infection pain worsened by swallowing, oral thrush, or being overstimulated. If this is happening regularly, discuss it with your pediatrician.
