Abstract
The purpose of this study is to describe foremilk volume (milk produced in the first 3 minutes of pumping), hindmilk volume (remainder of milk produced), and total milk volume produced by mothers of very preterm infants at 3 weeks postpartum and associated factors. Mothers (n = 24) mechanically pump their breasts a median (minimum, maximum) of 7 times (5, 9 times) per 24 hours for a total of 15 minutes (9.4, 23.9 minutes) each time. Foremilk, hindmilk, and total milk volumes are 183 mL per 24 hours (80, 810), 318 mL per 24 hours (98, 1007), and 545 mL per 24 hours (224, 1817), respectively. Milk volumes are not associated with mother's age, race or ethnic background, education, parity, reported prepregnancy body mass index, previous breastfeeding experience, frequency of milk pumping, longest time between pumps, infant birth weight, or multiple births. The degree of pre-maturity (<26 weeks vs 26(0/7)-27(6/7) weeks) is significantly related to the relative proportion of foremilk/hindmilk volumes (45:55 vs 36:65, respectively).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
