Problems of early infancy are sometimes managed by changing an infant's formula from a cow milk formula to a soy protein or casein hydrolysate formula ("special formulas"). This study was designed to determine the frequency of formula changes, mothers' reports of problems that lead to such a change, and mothers' beliefs about the causes of these problems. Mothers of 189 breast-feeding (BF) and 184 formula-feeding (FF) infants were enrolled postpartum. Follow-up data were obtained by telephone interviews at 4 months. After starting a cow milk formula, 11% of the BF and 25% of the FF infants were given special formulas. Mothers frequently reported problems related to feeding, bowel movements, and crying behavior; 32% of infants with such problems were given special formulas. Excessive crying and colic were the most common problems leading to a formula change. When a formula was changed, mothers more frequently believed that the cause of the problem was intrinsic to the child (P less than 0.001) and that their infant had had a "disease or illness" (P less than 0.001). When formula changes occurred, 26% of mothers believed that their infants were allergic to cow milk. These beliefs may affect a mother's perceptions of her child's vulnerability.
婴儿早期的问题有时可通过将婴儿配方奶从牛奶配方奶换成大豆蛋白或酪蛋白水解配方奶（“特殊配方奶”）来处理。本研究旨在确定配方奶更换的频率、母亲报告的导致此类更换的问题，以及母亲对这些问题原因的看法。189名母乳喂养（BF）婴儿和184名配方奶喂养（FF）婴儿的母亲在产后入组。在4个月时通过电话访谈获得随访数据。开始使用牛奶配方奶后，11%的母乳喂养婴儿和25%的配方奶喂养婴儿改用特殊配方奶。母亲们经常报告与喂养、排便和哭闹行为相关的问题；有此类问题的婴儿中32%改用特殊配方奶。过度哭闹和腹绞痛是导致配方奶更换的最常见问题。当更换配方奶时，母亲们更常认为问题的原因是孩子自身的（P<0.001），且她们的婴儿患有“疾病”（P<0.001）。当发生配方奶更换时，26%的母亲认为她们的婴儿对牛奶过敏。这些看法可能会影响母亲对孩子易感性的认知。
