^* Variables in the full model were: maternal age, method of delivery, parity, gestational age, time by which the infant was first put to the breast, whether the infant had received prelacteal feeds or been admitted to the special care nursery, period of time the infant was with the mother during the night while in hospital, mother’s BMI, whether the mother smoked prior to this pregnancy, and mother’s total IIFAS score.

^{† †} All variables in the final model were variables for which, when excluded, the change in deviance compared with the corresponding chi‐squared test statistics on the relevant degrees of freedom was significant.

^{‡ ‡} Adjusted odds ratios were derived from the logistic regression coefficients. BMI, body mass index; IIFAS, Iowa Infant Feeding Attitude Scale.
