1. Maintain breast cleanliness during pregnancy to prevent mastitis.
3. Breastfeeding is essential. Ensure adequate nutrition and quality sleep for the mother. Some mothers avoid breastfeeding to maintain their figure, but this is incorrect—breast milk is the most suitable food for a baby's growth.
4. Resume normal marital relations postpartum, but avoid indiscriminate use of estrogen. Estrogen not only promotes breast development but also induces systemic organ changes. If estrogen levels are low, consult a doctor before taking any medication.
