用法筆記

Lactation refers to the body's milk-making function (production and secretion), not to the act of feeding the baby at the breast. The feeding action itself is called breastfeeding or nursing.

用法筆記

Unlike sense 1 (the biological process), sense 2 names the whole time span — weeks or months — during which a mother produces milk and feeds her baby. The phrase 'lactation period' is a strong clue that sense 2 is intended.

常見錯誤

✅She is in the lactation period' or 'She is breastfeeding.
💡'Lactation' in sense 2 refers to a phase lasting weeks or months, not a single feeding session.
