Complementary feeding refers to the process of introducing solid foods to an infant's diet while continuing breastfeeding or formula feeding. This typically begins around six months of age, as babies need additional nutrients that breast milk or formula alone may not provide. The goal is to gradually introduce a variety of foods to help the child develop healthy eating habits. During complementary feeding, parents should offer a range of nutritious foods, including fruits, vegetables, grains, and proteins. It's important to ensure that the foods are appropriately prepared and safe for the baby to eat. This stage supports the child's growth and development while helping them learn to enjoy different flavors and textures.
