L., stick with your mommy instincts. If you feel something is not right, I say do something about it, you know your child better than the dr. I would also say that even if you totally respect your dr's opinion, I would still get a 2nd opinion. My child had RSV at age 1, and our stories sound similar. Anyhow, after a few years of back and forth at the ER for breathing treatments, and wondering what the heck was actually wrong, I took him to Dr. Jeff Wald at Kansas City Allergy and Asthma. What a difference he made in my son's life. Yes, he had asthma brought on by the outside elements. He would start with coughing and a clear runny nose and seem to have allergies, them BOOM the asthma would kick in. He has not totally outgrown it yet,at age 12, but is much better with Dr. Wald's assistance. He is on Singulair, and just got taken off Pulmicort and put on a new drug called Symbicort, which is Pulmicort and inhaler combined as I was explained. Anyhow, what I am trying to say is don't be afraid to go to a different Dr. because your daughter cannot speak for herself, I just think a specialist would not go the extra mile and figure it out for sure. I'm sure glad I went. Also, be prepared that your daughter may have allergy problems. My son did, and I put him on their shot program at Dr. Walds, it was a pain, and a 5 year program,with weekly shot visits, but he has almost no allergy problems anymore. Their program just "revamps" your immune system so you don't suffer severly from allergies. I'm not sure what they would do for a baby, because by the time we started the shot program my son was 5 or 6. But I would not change it for a thing. His life was changed because of the visit to the asthma dr. Good luck to you and your daughter.
