Most babies start hugging between 10 and 18 months old. You’ll likely notice the earliest versions around the end of the first year, when your baby wraps their arms around your neck or leans into your chest. These first hugs are brief and clumsy, but they’re intentional acts of affection. By 18 to 24 months, toddlers typically show affection with hugs, kisses, and cuddling directed at both people and favorite toys.
What Needs to Happen Before a Baby Can Hug
Hugging looks simple, but it actually requires several physical and emotional skills working together. Your baby needs enough trunk stability to sit upright without support (most babies achieve this between 6 and 8 months), the arm strength and coordination to reach out and wrap both arms around something, and the social awareness to understand that pressing their body against yours is a way to express closeness.
Before about 6 months, babies show affection in other ways: making eye contact, smiling, cooing, and nestling into you when held. These are precursors to hugging, not substitutes for it. The shift from passively being held to actively holding you back is a significant developmental leap that combines gross motor control with emotional understanding. Between 9 and 11 months, babies gain the ability to move between lying down and sitting without help, giving them the core strength and body control that makes a real hug possible.
The Typical Timeline
Around 9 to 12 months, many babies begin leaning into a parent during a cuddle or pressing their face against your cheek. This is the earliest recognizable form of a hug, though it may not include wrapping both arms around you. At this age, babies are also starting to play interactive games like pat-a-cake, which shows the kind of social back-and-forth that hugging builds on.
Between 12 and 15 months, hugs become more deliberate. Your baby may toddle over and throw their arms around your legs, or reach up to be picked up and then squeeze your neck. They’re starting to understand that a hug is something they can initiate, not just receive.
By 18 to 24 months, hugging is a well-established part of a toddler’s social toolkit. Cleveland Clinic lists showing affection with hugs, kisses, or cuddling (directed at you or a toy) as a typical milestone during this period. You’ll often see toddlers hugging stuffed animals, dolls, pets, and sometimes other children, though peer hugging can be awkward and one-sided at this age since both kids need the same skills.
Why Hugging Matters for Development
Physical affection between a parent and baby triggers the release of oxytocin, sometimes called the “hormone of attachment,” in both of you simultaneously. Research published in the International Journal of Nursing Sciences found that during skin-to-skin contact, oxytocin levels increased in infants, mothers, and fathers alike. Parents with higher oxytocin levels showed more responsiveness and synchrony in their interactions, creating a positive feedback loop.
Oxytocin does more than just feel good. It helps regulate the autonomic nervous system, which controls heart rate, breathing, and stress responses. During close physical contact, babies’ cortisol (the stress hormone) drops measurably. Studies show salivary cortisol in infants was lower during parent-infant interaction than before or after, with a clear inverse relationship between oxytocin and cortisol. In practical terms, hugging genuinely calms your baby at a physiological level.
There’s also a cross-generational effect. Infant oxytocin levels correlate with their mother’s oxytocin levels, suggesting that caregiving physically shapes a baby’s capacity for bonding. These early bio-behavioral experiences within the parent-infant bond influence a child’s social behavior across multiple relationships as they grow, strengthening the brain structures that control emotions and behavior through repeated positive reinforcement.
When Babies Don’t Seem to Like Hugging
Some babies resist being held closely, arch away during cuddles, or stiffen when you try to hug them. This is often just temperament. Babies have individual sensory preferences from birth, and some are simply less comfortable with sustained close contact. A baby who squirms out of a hug may prefer other forms of connection, like face-to-face play, hand-holding, or sitting in your lap without being squeezed.
Tactile avoidance in babies can stem from several things. Some babies are more sensitive to the feeling of pressure or being constrained. Others show what researchers describe as negative emotionality, a heightened distress response to novel or overwhelming stimuli that isn’t specific to touch. A baby who pushes away during a hug might be reacting to feeling restricted rather than rejecting affection itself. Context matters too: a baby who’s overstimulated, tired, or focused on exploring may resist a hug simply because the timing is wrong.
Persistent and significant avoidance of all physical contact, especially when combined with limited eye contact and lack of social engagement, can sometimes be an early indicator worth discussing with your pediatrician. But on its own, not wanting to hug is well within the range of normal infant behavior. Many kids who aren’t huggers as babies become more physically affectionate as toddlers once they have the autonomy to initiate contact on their own terms.
How to Encourage Hugging
You don’t need to teach a baby to hug, but you can create the conditions for it. Holding your baby close during calm, happy moments (not just when they’re upset) helps them associate physical closeness with positive feelings rather than only with comfort-seeking. Narrating what you’re doing helps too: saying “hug!” while you embrace them gives them a word for the action.
Modeling matters. When your baby sees you hug your partner, a family member, or even a stuffed animal, they learn that hugging is a normal social behavior. Many toddlers practice hugging on dolls and stuffed animals before consistently hugging people, so handing them a soft toy and showing them how to give it a squeeze can be a useful stepping stone.
If your baby does hug you, even clumsily, respond with warmth. Smiling, hugging back, and using a warm tone reinforces the behavior through the same oxytocin-driven positive feedback loop that makes physical affection feel rewarding for both of you. Over time, these small moments of reciprocal affection build the neural pathways that support social bonding well beyond infancy.
