After birth, babies usually need to be exclusively breastfed for at least 4 months, and complementary foods can be added gradually at 4-6 months depending on the baby’s condition, and weaning can be done gradually at 10-12 months. Breast milk is the best and irreplaceable nutritional product when your baby is first born, providing nutrients and improving your baby’s immunity, so it is recommended to exclusively breastfeed your baby for at least 4 months. 4-6 months old, you can gradually add water juice and paste to your baby to provide nutrition and prepare for weaning later. After 6 months, as your baby develops, the quality and quantity of breast milk can no longer meet your baby’s growth needs, so you must add complementary foods, gradually reduce the number of feedings, and pay attention to calcium supplementation. 10-12 months can be gradually weaned completely. Most babies will be weaned after 1 week of age. If the amount of breast milk is high, it can be extended to 1.5-2 years old, but it should be noted that breastfeeding is too long and easy to consume the body of the breastfeeding mother, which may cause osteoporosis.
