The American Academy of Pediatrics (AAP) recommends that infants spend supervised time in the prone (tummy) position to foster motor development and prevent cranial deformities. However, infants may not tolerate the position, and consequently, caregivers may avoid placing their infants in the prone position. The AAP recommends that caregivers provide toys or interaction during tummy time. We evaluated the individual and combined effects of a play mat and experimenter interaction on negative vocalizations and head elevation during tummy time-positive effects were limited. Next, we evaluated a parent-led intervention wherein mothers interacted with their infants, using a toy, while lying chest-to-chest. This intervention was associated with a reduction in negative vocalizations and an increase in head elevation for the majority of infants. Additionally, mothers rated the effectiveness of the parent-led intervention more favorably than the experimenter-led intervention, suggesting the effects of the parent-led intervention were also socially valid.
美国儿科学会 (AAP) 建议婴儿在有监督的情况下俯卧（肚子朝下），以促进运动发育并防止头部畸形。然而，婴儿可能无法忍受这种姿势，因此照顾者可能会避免让婴儿俯卧。AAP 建议照顾者在婴儿肚子朝下时提供玩具或互动。我们评估了游戏垫和实验者互动对婴儿负面发声和头部抬高的单独和综合影响——积极影响有限。接下来，我们评估了一种由母亲主导的干预措施，其中母亲与婴儿进行互动，使用玩具，同时胸贴胸躺着。这种干预措施与大多数婴儿的负面发声减少和头部抬高增加有关。此外，母亲对由母亲主导的干预措施的有效性评价要优于实验者主导的干预措施，这表明由母亲主导的干预措施在社会上也是有效的。
