Newborns weighing at birth and their mothers who deliver within the study’s defined time frame and who consent within 24 hours.

What this trial studies
This observational study collects data on newborn weights during the first five days after birth. Researchers will record birth details, maternal factors, and feeding type to explore how timing of weight measurements relates to weight loss and breastfeeding outcomes. The goal is to inform when weighing should occur to optimize breastfeeding support and maternal mental health. No interventions are described beyond standard weighing performed by maternity staff. Results may guide clinical practice and policy on newborn weight monitoring in the immediate postnatal period.
Why it matters
Potential benefit: If successful, the findings could optimize timing for newborn weighing to support exclusive breastfeeding and maternal well-being.
How similar studies have gone: Previous research has used observational weight tracking to inform breastfeeding practices, but this specific timing question is not well established.
