A new longitudinal study finds that babies begin helping their caregivers as early as their first year of life — and the way they learn to help depends heavily on everyday routines, parental modeling, and developing motor skills.
Long before a child can speak in full sentences, they may already be handing you the sock you dropped or sliding their arm into a sleeve to make dressing easier. A new study published in Child Development, a journal of the Society for Research in Child Development, sheds light on why infants start helping so early — and what shapes that behavior over time.
Researchers at Ludwig-Maximilians-Universität München (LMU Munich) in Germany tracked 118 mother-infant pairs at three points in time — when infants were six, 10 and 14 months old — to understand how helping behavior emerges and evolves. Their findings reveal that early helpfulness is not a single, uniform trait but rather two distinct developmental pathways depending on who the baby is trying to help.
Helping a Caregiver vs. Helping a Stranger
The study found that when infants help their primary caregivers — folding laundry together, placing books on a shelf, or assisting with other shared routines — that behavior is closely tied to maternal modeling. In other words, the more a caregiver demonstrated helpful actions, the more likely the infant was to pitch in. This suggests that helping a familiar person is largely driven by concrete situational cues the child has seen and absorbed during daily interactions.
Helping an unfamiliar adult, by contrast, operated through a different mechanism. That behavior was more strongly connected to an infant’s ability to understand another person’s goals and to whether the infant had experienced sensitive, responsive caregiving — meaning the caregiver consistently noticed and appropriately responded to the baby’s cues and needs.
The research team also found that motor development played a meaningful role. Infants who had more advanced motor skills were better positioned to act on their helpful impulses, underscoring the link between physical capability and prosocial behavior at this early stage.
Why It Matters
For college students studying child development, education, psychology or social work — and for anyone who will one day raise children or work with them — these findings carry practical weight. The research suggests that helping behavior is not simply innate or fixed; it is shaped by the quality of early interactions and by the environments children are raised in.
The research team noted that involving infants in shared routines, demonstrating helpful behavior, and responding attentively to an infant’s signaled needs may all support a child’s tendency to help others over time. Early childhood educators and family practitioners could use these insights to design environments and interactions that nurture prosocial development from the very first year of life.
The study also advances scientific understanding of prosocial behavior more broadly. Helpfulness, the researchers point out, is one form of prosocial action — behavior that benefits another person. Their data indicate that even in infancy, such behavior is already being shaped by individual capabilities like motor control and social cognition, as well as by relational experiences.
Limitations and What Comes Next
The researchers were transparent about several constraints. The study assessed helping toward caregivers and strangers at the same developmental time points rather than across different stages, which limits conclusions about how those trajectories diverge over a longer arc of development. The laboratory setting, while useful for standardized measurement, may not fully capture the variety of helping moments that unfold naturally at home.
Future work, the team noted, should examine how helping in everyday, naturalistic settings compares to behavior observed under controlled conditions. Researchers are also interested in exploring how different types of prosocial behavior — including emotional support and sharing — develop along their own unique pathways.
