DO NOT DO NOT DO NOT DO NOT go to Parnes May and Associates in Columbia, Maryland. They never diagnosed our son, even with 2 hospitalizations, numerous colds and bowel problems, but the age of 3. We were even yelled at by Parnes that, "Children get colds! We will not give you more antibiotics!" Only to find he has CF... but not until his sister was born and almost died of MI. Even two days after I gave birth, and his sister was confirmed CF, they still told me our son didn't have it. If she had not been born, he would have died of pnemonia last winter. I DO NOT trust peditricians at all!!
