Solid Foods: How Much & When. A baby drinks the majority of her calories until about 7 to 10 months. So at mealtime, feed breast milk or formula first, before the solid food. At about 9 months, flip-flop the order and begin giving food first.
After about 4-6 months, you can probably introduce your child to something besides breast milk or formula. But even then, there is no need to rush. Your baby needs to be physically and developmentally ready for solid foods. When introduced too early, solid foods can be hard to digest. Here are some signs that your baby might be ready for food: 1  Your baby can sit with little support. 2  Your baby can move food from the front to the back of the mouth. 3  Your baby shows interest in the foods you are eating. 4  Your baby's weight has doubled since birth.
