As the immune system continues to develop you can expect baby to get sick a lot. Every new pathogen encountered will mount an immune response, whereby baby will create antibodies, building the immune system’s defence mechanism. As the immune system matures, the number of illnesses drops, because the immune system has learned how to respond.
By providing baby with a balanced, nutritious diet, you can help to support the normal function of the cells and tissues that make up the immune system. While you can’t necessarily prevent baby from getting sick, a healthy diet can improve the body’s immune response and decrease recovery time.
