The best time to wean infants and toddlers is usually around one year of age, but the exact weaning age varies and there are some differences between individuals. Infants and young children are in a period of rapid growth and development and need more nutrients. In general, it is recommended to breastfeed until about one year of age, relying solely on breastfeeding can not meet the nutritional needs of infants and young children, so they need to be weaned in order to obtain sufficient nutrients from food. However, abrupt weaning is not recommended. Gradual weaning can be initiated by reducing breastfeeding after infants start to consume solid food at 6 months of age. Weaning can be started by feeding rice paste and vegetable juice at around six months of age, thicker vegetable porridge at around nine months of age, and reducing the frequency of night feeds one by one. Weaning is basically completed when the baby is able to eat softer, chopped vegetables at around one year of age.
