Distribution of infant feeding groups as observed and as estimated in response to hypothetical changes in hospital feeding practices. Categories of feeding in previous 24 h: EBF, exclusively breastfed; BF&L, fed breastmilk and non-milk liquids; MF, mixed feeding of breastmilk and animal milk or formula; BF&S, fed breastmilk and solid or semi-solid foods; NBF, not breastfed. Notes: The stacked bars represent the distribution of current feeding groups under five separate scenarios for hospital feeding practices: observed (first bar) and in response to one of the four simulated interventions. Each bar represents all children in the analytic sample and either their observed or hypothetical current feeding group membership (i.e., total equals 100%). To set 25% of the sample to receive formula, infants’ probability of receiving formula was predicted using logistic regression and the same factors used to explain current feeding practice. These probabilities were then scaled such that the overall average was 25%. Infants’ simulated formula feeding experience was drawn from a Bernoulli distribution with probability equal to their down-scaled probability
