Breastfeeding can usually be considered at around one year of age and should not be done later than one and a half years of age. When the child is about one year old, parents can consider weaning the child from breast milk, because as the child grows and develops, the nutrients in breast milk may not be able to fully meet the child’s growth and development needs. If the child is not breastfed at this time, it may affect the child’s normal complementary food and nutrient intake, which is not conducive to the child’s growth and development. In general, when the child is about five months old, it is necessary to add complementary foods appropriately, and when the child is about one year old, it can usually eat soft noodles, rice, and vegetables and fruits, etc. At this time, weaning off breast milk, the child can get nutrients from these foods, and it will not affect the child’s nutritional intake.
