Weaning is the process of gradually introducing an infant or young animal to solid food while reducing their dependence on breast milk or formula. This transition typically begins around six months of age for human babies, as they start to develop the ability to digest more complex foods. During weaning, caregivers often offer a variety of pureed foods and soft solids to help the child adapt. The process can take several months, and it is important to ensure that the child receives adequate nutrition from both solid foods and remaining milk sources during this time.
