Recent research indicates that there are identifiable and important characteristics of the day care environment that influence its quality and, ultimately, the psychological development of infants and toddlers. An analysis of existing licensing requirements reveals great variation among the 50 states in standards for infant and toddler day care. This absence of a uniform standard translates into a wide range of questionable experience for these very young children.
最近的研究表明，日托环境存在一些可识别的重要特征，这些特征会影响其质量，并最终影响婴幼儿的心理发展。对现有许可要求的分析显示，50个州在婴幼儿日托标准方面存在很大差异。缺乏统一标准给这些非常年幼的儿童带来了广泛的、质量存疑的体验。
