Hi C.-
Reading your story and the stories of other moms and kids is breaking my heart. All these medications into all the little babies and kids without the relief that you're looking for.
Have you condsidered taking your child to a pediatric chiropractor? While this is not the "magic bullet" answer, it may be something that can help. I am a pediatric chiropractor in Overland Park, Kansas, and I agree with many of the respondants that there seems to be A LOT of sinus/cough/congestion going around this year. I see it in many of my patients, but we can usually get it under control in a few days to weeks with adjustments and natural remedies. I even had a 3 1/2 week old patient with RSV recently who almost passed away in the hospital... after only one adjustment, they took her off oxygen and no longer needed to do her respiratory treatments. Unfortunately, a few weeks later she was diagnosed with "reflux" and put on more medication. Two more adjustments and she's doing very well. My point being, most people don't know how powerful chiropractic care can be to the immune & respiratory systems. I hope that you will look into it.
I strongly encourage you to find a chiropractor who specializes in pediatric care. You can do this at www.icap4kids.org. Just click on find a doctor. While I am not in your area, please also consider me a resource. I would be happy to answer any questions that you have.
Once you get things under control, I also agree that you may need to look into allergy testing for your little one. I also recommend naturopathy/homeopathy. Doctors who work in these areas tend to use herbal/natural methods that work WITH the body rather than searching for chemical means to counteract what the body is doing.
FYI- a great resource for natural baby care is Natural Baby and Childcare: Practical Medical Advice and Holistic Wisdom for Raising Healthy Children by Lauren Feder, MD. There is a TON of great information. Dr. Feder is a medical pediatrician who practices homeopathy.
I wish you and your family better health and better answers...
Yours in health,
Dr. Alyssa
