Primiparous mothers and their infants who had an extra 15-20 minutes' suckling and skin to skin contact during the first hour after delivery, behaved differently at 36 hours post partum compared with a control group without this extra contact. The present study is a 3-month follow-up of these mothers and infants by means of direct observation of mother-infant free play and a personal interview with the mothers. Mothers in the extra contact group spent more time kissing and looking en face at their infants; these infants smiled more often and cried less frequently. A greater proportion of the mothers with extra contact were still breast feeding at 3 months. The influence of extra contact on behaviour was more pronounced in boy-mother than in girl-mother pairs.
初产妇及其婴儿在分娩后第一小时内若有额外15至20分钟的哺乳及皮肤接触，与未进行这种额外接触的对照组相比，产后36小时的行为表现有所不同。本研究对这些母婴进行了为期3个月的随访，通过直接观察母婴自由玩耍情况以及与母亲进行个人访谈来进行。额外接触组的母亲花更多时间亲吻婴儿并与婴儿面对面注视；这些婴儿微笑更频繁，哭泣更不频繁。额外接触组中有更大比例的母亲在3个月时仍在进行母乳喂养。额外接触对行为的影响在母婴为男孩的对子中比在母婴为女孩的对子中更为明显。
