Kids Eat a Lot of Carbohydrates

Parent Stories
“My son, Jarrod, was in first grade. Upset and withdrawn after school, he finally told me at bedtime that he had diarrhea during recess and had to change clothes in the nurse’s office. The other kids were teasing him, calling him awful names like ‘stinky’ and ‘poopy pants.’ I was devastated. I knew it was time to talk to our doctor.”
“As a mother, it is devastating to watch your baby deteriorate before your eyes and not know what is causing him to react to certain foods in this horrifying way. To get the proper diagnosis and then to be able to manage his diet with the right foods and therapy has been just what we needed.”
“When my son was first diagnosed with CSID and I realized how much his diet needed to be restricted, I thought it might be near impossible and I feared his diet would be so restricted that it would be unhealthy … After a year or so with therapy, my son felt like he could eat more like a normal kid!”
