Lactose‐Free Milk or Soy‐Based Formulas Do Not Improve Caregivers' Distress or Perceptions of Difficult Infant Behavior

Abstract

Our study does not support LF milk or LF soy-based formulas to alleviate common infant behaviors such as fussiness, crying, or need for attention. Moreover, the data suggest that some difficulties in infant behaviors, as well as caregivers' distress and perceived efficacy in parenting difficult infants, may improve within a couple weeks of reporting difficulties to the pediatrician.
