When a food is labeled organic, it is grown without the use of synthetic pesticides, hormones, genetic modification, antibiotics, or chemicals (source).  These foods typically have a higher level of antioxidants, and certain nutrients such as iron and vitamin C. Babies are more sensitive to pesticides than adults.  Their kidneys are unable to effectively process and expel pesticides from the body.  These chemicals can also adversely effect hormone functions and brain development (source).  Some studies have shown an association between pesticide exposure and autism (source). Unfortunately, organic produce is going to cost you more.  If you are on a budget, get what you think is best for your baby.  In fact, the USDA makes no claims that organic is safer than non-organic foods, and the American Academy of Pediatrics agrees (source).  In addition, organic food tends to spoil faster.  Most importantly, remember that you are a great mom, regardless of whether or not your baby eats organic baby foods.
