Prevalence (± SE) of excess neonatal weight loss (weight loss > 10 % of birth weight; restricted to infants consuming < 60 mL of formula over the first 72 h; n = 218 with BMI data) by timing of
onset of lactogenesis (OL), stratified by maternal BMI group.
Parker, L.A., Sullivan, S., Krueger, C. & Mueller, M. Association of timing of initiation of breastmilk expression on milk volume and
timing of lactogenesis stage II among mothers of very low - birth - weight infants.
Initial BMI data was recorded during pregnancy and correlated to the onset
of lactogenesis 2, the stage after colostrum when milk begins to flow.
