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.
There are several other indicators that your baby is ready to start solid foods. 1  First, note that the AAP recommends breastfeeding as the sole source of nutrition for your baby for about 6 months. In addition, they advise that most babies are ready to start solid foods when they reach the following milestones: 1  They can sit in a high chair or feeding chair and hold their head upright. 2  They can open their mouths as food comes their way. 3  They can move food from their mouth to their throat.
