“I’m in love.”
“No, you’re not. You don’t know what love is. You love cupcakes and ponies.” – Steve Byrne, The Byrne Identity

Kids are funny when it comes to love. Adults see it as a deep emotional connection, but children are still figuring out what that feeling even is. They might say “I love you” to a parent, announce plans to marry a playground friend, or juggle “relationships” with multiple classmates. They hug with their whole bodies and may even offer a kiss simply because they don’t know another way to show affection.

Kids may not fully grasp what love means, but they’re learning how it feels, how to express it, and how to set safe boundaries—and that learning begins from the moment they’re born.

The Development of Love

Kids don’t experience love as a single, defined feeling the way adults do. Instead, it unfolds in stages, each tied to brain development, attachment, and social learning.

• Infants. For babies, love is felt as safety and regulation rather than understood as an idea. Warmth, feeding, eye contact, and soothing create their earliest sense of security. Over time, their brains wire around these repeated experiences. With consistent, responsive care, they form secure attachment, which becomes the foundation for how they understand relationships later in life.
  
  
• Toddlers. At this age, toddlers show affection through imitation and proximity. They hug tightly, bring toys to share, and trail trusted adults from room to room. They don’t yet understand reciprocity, but they do understand closeness and belonging. And because their emotional regulation is still developing, love and frustration often appear in tandem and at full volume. Hello tantrums…
  
  
• Preschoolers. Around ages 3–5, children start to understand love as caring about someone else’s feelings. They’re learning that other people have emotions separate from their own, and love shows up in their desire to help, comfort, or share. They also express affection through language and small rituals; think enthusiastic “I love yous,” handmade cards, drawings, and little gifts. So, if you ever wonder whether your child loves you, just look at the artwork covering your fridge.
  
  
• Early Elementary. Between first and third grade, kids begin to see love as loyalty and fairness. They start connecting love with values like kindness, sticking by a friend, and “being there” for someone. At this age, they can reflect on what makes them feel loved and what makes others feel loved. They also begin to understand that love can remain steady even when someone isn’t physically present.
  
  
• Later Childhood. Around ages 8–12, kids can hold more nuanced ideas, recognizing that love can include conflict, repair, and compromise. They begin to differentiate between types of love (family, friendship, admiration, and early crushes/attraction) and they can reflect on their emotional experiences with much more depth.

Love on the Brain (Kid Edition)

Adults can experience love as something intense or dramatic (yearning Conrad Fisher), but children feel it through attachment and regulation. In their world, love simply feels like being safe and cared for. Their brains don’t show the dopamine‑driven patterns associated with romantic love simply because their brains aren’t wired for it yet. Instead, they reflect attachment processes.

Studies show that early caregiving experiences sculpt the emotional and regulatory systems of the brain:

• Attachment is a biological process. Neuroscience shows that early love and connection literally shape a child’s developing brain. Repeated warm social interactions help wire healthy pathways, and oxytocin (the love hormone), rises during these moments to support feelings of love and connection.
  
  
• Learning safety through loving care. In infancy, the amygdala (the emotional alarm system) is highly sensitive, and takes its cues from caregivers. Consistent warmth teaches the amygdala that the world is safe, while inconsistent or cold care can make it overactive, increasing long‑term anxiety and hypervigilance.
  
  
• Regulation develops through relationships. The prefrontal cortex (responsible for skills like emotion regulation, impulse control, and decision making) is immature in children and grows in response to caregiver interactions. Studies show that when caregivers and infants share warm and positive moments together, they become physically “in sync,” with their heart rates, stress hormones, and oxytocin levels. Secure attachment strengthens the ability to self-regulate while inconsistent or insecure care can hinder it.

Love in childhood serves as a neural blueprint that shapes how a child will relate, regulate, and connect throughout life. Children don’t learn what love is from a single moment or definition; they learn it gradually through thousands of everyday interactions. Still, that doesn’t mean they fully understand those feelings or know how to express love appropriately yet.

Trial and Error of PDAs

When a child says “I love my friend” or tries to kiss them, it’s almost always a normal expression of affection, curiosity, and social learning—not a romantic impulse. Kids are experimenting with the language and rituals of love long before they understand the adult meaning behind them. Because their emotional vocabulary is still small, “love” becomes their strongest word for closeness. It’s their way of saying “I like you,” “you’re fun,” or “you matter to me,” and it reflects a genuine sense of connection.

Children also learn by imitation. The affection they see around them (parents hugging, characters in media showing warmth, friends being close, etc.) influences how they express their own feelings. They’re also testing social boundaries, figuring out what kinds of affection are okay and how others respond. These moments aren’t romantic; they’re part of learning how relationships work.

When a child says “I love you” to a friend, they’re practicing empathy and attachment. They’re showing emotional awareness, affection, and a desire for connection, all of which are healthy signs of social‑emotional development. Unless a child has been exposed to inappropriate content or experiences (which would show up in other ways btw), gestures like hugging or kissing are innocent and exploratory. They simply show that a child’s social‑emotional world is expanding.

Love Lessons

The way kids come to understand love helps shape many essential skills, such as:

• Secure attachments – builds emotional resilience, helping them cope with stress and form healthy relationships
• Empathy – helps kids read emotions and understand others’ perspectives
• Identity – provides a stable base to explore who they are and what they can do
• Executive function – strengthens self-regulation, attention, and problem‑solving, which improve learning
• Social skills – observation of behaviors of how to treat people we care for regarding communication, boundaries, repair, affection, and respect

Kids don’t automatically know how to express affection, set boundaries, or read social cues (please see above); however, parents play a powerful role in helping them learn what love is and how to show it in ways that feel good to them and to others. Here are some ways to support children as they learn to express love and affection appropriately:

• Model affection. Children learn far more from what they see than what they’re told. When adults show calm, open affection (using gentle touch, warm tone, eye contact, and asking for consent like “Can I give you a hug?”) kids absorb those patterns. They come to understand that love feels safe and steady, not overwhelming.
  
  
• Narrate emotional experiences. Putting words to feelings helps kids understand what love means. When adults say things like, “You feel close to Grandpa because she reads with you,” “You’re showing love by helping your brother,” or “It feels good when someone listens to you,” children build emotional vocabulary and a clearer sense of what connection feels like.
  
  
• Teach boundaries without shame. Kids need gentle guidance on how to show affection in ways that respect others. Simple reminders like “We save kisses for family,” and “We always check first” help them learn consent and what’s appropriate.
  
  
• Reinforce consent and reading cues. Children need gentle guidance on showing affection in ways that respect others. Simple cues like “If your friend steps back, that means they want space,” or “If someone says no to a hug, we try something else,” help them understand how to read cues and body language. They learn that love is something shared, not one‑sided.
  
  
• Offer alternatives to expressing love. Kids often default to the strongest gesture they know, so giving them options helps. They can draw a picture, say something kind, share a toy, or invite someone to play. Offering these alternatives expands their “love language” toolkit and shows them many ways to express connection.
  
  
• Celebrate empathy and kindness. Notice and name the moments when your child shows love in healthy ways. When you say things like “You comforted her when she was sad. That was kind of you,” or “You shared your snack because you wanted him to feel included,” you reinforce the behaviors you want to grow and help your kid recognize what loving actions look and feel like.
  
  
• Keep affection connected to safety and regulation. For younger children, love is closely tied to co‑regulation. A calm presence, predictable routines, and repair after conflict all help their nervous systems settle and feel safe. Through these repeated experiences, children learn that love is steady and dependable, not conditional.
  
  
• Use stories, books, and play. Children pick up social rules by acting things out in stories and pretend play. Reading books about friendship and feelings, role-playing how to ask for a hug, and talking about characters’ emotions all give them simple scripts they can use in real life.
