No intervention is needed for this 1-day-old girl as she is exhibiting normal physiologic findings. The enlarged mammary glands, swollen labia, and blood-tinged vaginal discharge are all common findings in newborn females due to maternal hormone exposure. During pregnancy, maternal estrogen crosses the placenta and affects the newborn's tissues. After birth, when these hormone levels drop, the newborn may experience these transient changes. The blood-tinged vaginal discharge, often called pseudomenstruation, typically resolves within the first week of life. The breast enlargement may persist for several weeks before gradually resolving. Parents should be reassured that these findings are normal and self-limiting. No medications, treatments, or special care is required beyond routine newborn care. However, if the discharge becomes purulent, foul-smelling, or if the breast tissue becomes red, warm, or tender, medical evaluation would be warranted as these could indicate infection rather than normal physiologic changes. The provided evidence 1, 2, 3, 4 does not directly relate to the normal physiologic findings in newborns, but it is essential to note that the management of sepsis and infections, as discussed in the studies 1, 2, 3, is crucial in cases where infection is suspected. In this case, however, the clinical presentation is consistent with normal newborn physiology, and therefore, no intervention is necessary.
