Hi. I have a 7 year old son. We recently moved to a new state. My son had a cough that wouldn't go away and the first time seeing this Pediatrician she starts talking about how little my son is and because he was diagnosed with Pneumonia and Bronchitis within the past year and a few other issues when he was little that required Albuterol, she said wanted to test him for Cystic Fibrosis if he didn't get better in two weeks. Well, he got better and I requested a different doctor in the same group. He diagnosed Asthma and said nothing about Cystic Fibrosis. However, a month later he is now sick again. Started off like a cold but it is just lingering (like a lot of his colds). He was tested for CF as a newborn and he tested Negative. When he was born he the same weight as my daughter (6 pounds) and he was a chubby baby until I quit breastfeeding and then he lost a lot of weight. He did have reflux when he was born and took medicine for that. He is in the 5th percentile for his Height and 3rd percentile for his weight. I try to push food on him all the time but he just isn't a big eater. My point is my husband and I are short people. My husband is 5'5 and I am 5'2. I have this knot in my stomach and I really hate that I might have to bring him back to the doctor soon. I know this post is skipping around and sorts but I am just sick about my son. I feel like in the pit of my stomach he might have Cystic Fibrosis with everything that I have read. I am really scared to bring him back to the doctor. I don't think I a am asking a question here but maybe someone can tell me something to help me over this next hurdle.
