Mother--child interaction was studied on the 2nd and 4th days after delivery. Mothers with girls showed more distal contact behaviour such as talking, smiling, and 'en face' responses. They also displayed more skin-to-skin contact behaviour (patting, rubbing, kissing, and touching) toward girl babies. Mothers with boys, on the other hand, showed more types of behaviours directed to clothed parts of the infant such as patting and adjusting clothes. These findings were statistically significant only on the 2nd day after delivery. On day 4 differences between male and female infants both in the frequency and in the pattern of sucking were observed.
在分娩后的第2天和第4天对母婴互动进行了研究。生女孩的母亲表现出更多的远距离接触行为,如交谈、微笑和“面对面”反应。她们对女婴也表现出更多的肌肤接触行为(轻拍、抚摸、亲吻和触摸)。另一方面,生男孩的母亲表现出更多针对婴儿穿着部位的行为,如轻拍和整理衣服。这些发现仅在分娩后的第2天具有统计学意义。在第4天,观察到男婴和女婴在吸吮频率和模式上的差异。
