Transitions in Breastfeeding: Daily Parent Diaries Provide Evidence of Behavior Over Time
Bibliographic record
Abstract
This study addressed a key question for assessing breastfeeding duration: at what point is an infant considered no longer exclusively breastfed or no longer breastfed at all? Mothers provided longitudinal infant feeding data via daily checklists. Transitions between exclusive to partial breastfeeding and partial to no breastfeeding were compared across 11 time periods for 10 age groups of infants. Daily transitions between exclusive and partial breastfeeding were common, especially for infants 6 months of age and younger, and transitions from partial to no breastfeeding occurred much more quickly than transitions from exclusive to partial breast-feeding. Ages at supplementation and weaning calculated in 1-day or 7-day spans correlated highly (intraclass correlation = .99). These results support the Breastfeeding Definitions and Data Collection Periods guideline recently developed by the Breastfeeding Committee for Canada and may bring the breastfeeding research and clinical communities closer to a consensus on the definition of breastfeeding over time.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
