Why Are Many Children Closer to Their Mother’s Side of the Family? A Look at the Science of Imprinting
During pregnancy, a mother’s social environment often includes frequent interactions with people from her own family i.e., her siblings, parents, cousins, aunts, and uncles. These are often the individuals who call, visit, offer support, and whom she speaks about most often. The developing baby, while still in the womb, is sensitive to the mother’s emotional states and physiological responses. When the mother experiences comfort, familiarity, or joy in relation to these people, those emotional signals can influence the baby’s early associations.
After birth, these same relatives often continue to play a prominent emotional role in the child’s environment. Importantly, this exposure is not only physical but emotional through the tone of conversations, the warmth in interactions, and the feelings the mother expresses when discussing or engaging with them. Over time, these repeated emotional cues may contribute to a subtle form of imprinting, shaping the child’s sense of familiarity and comfort.
This may help explain why, even if a child has not seen a maternal relative for a long time, they can sometimes reconnect quickly and feel an immediate sense of ease. Early emotional associations formed before and shortly after birth can leave lasting impressions that influence how relationships develop later in life.
How Can Relatives on the Father’s Side Imprint More Strongly?
Imprinting, however, is not fixed. Emotional bonding continues to develop throughout childhood, meaning that relatives on the father’s side can also build strong imprints if they are consistently present in the child’s emotional environment.
When paternal relatives frequently visit, spend meaningful time with the child, participate in caregiving, or are spoken about positively and often within the household, they too become part of the child’s emotional landscape. If the father actively maintains close ties with his family and integrates them into daily family life through visits, shared experiences, storytelling, celebrations, or support during important moments the child begins to associate those relatives with safety, familiarity, and affection.
In essence, imprinting strengthens through repeated emotional experiences. When paternal relatives provide warmth, engagement, and reliability, the child forms the same sense of comfort and belonging with them. Over time, these interactions can build bonds that are just as strong, sometimes even stronger than those with maternal relatives.
Ultimately, closeness in families is less about which side someone belongs to and more about who is emotionally present, consistent, and involved in a child’s life.
