While it goes without saying that during pregnancy the mother absolutely needs to eat a clean, and highly nourishing diet including prenatal vitamins for proper fetus development, the concern for nutrition does not stop here. Proper infant and child nutrition is of vital importance for the growth and development of strong organs and body. The order of introduction of foods and breastfeeding are critically important in building a hearty immune system. Probiotics can be introduced in infancy to promote good gut health at a very young age and toddlers can be introduced to fish oils to enhance brain development. While the mother is pregnant and breastfeeding, it is desirable to take probiotics and fish oils along with the prenatal vitamins as the baby will receive the nutrients that the mother is ingesting.
