This cross-sectional study reviewed infant feeding regulations for all U.S. states for child care centers and family child care homes, then compared the regulations with ten national standards and also assessed the number of new regulations consistent with these standards since a previous review conducted in 2008. The 2008 review found that the majority of states lacked regulations consistent with the standards. This current review found significant improvements in seven of the ten standards for child care centers and four of the ten standards for family child care homes. The study concluded that many states are and have been making efforts to implement new regulations to improve infant feeding in child care and highlights the importance of state regulations to continue these efforts.
