I have a 6 year old daughter that has been bothered with a really bad caught since she s been about 2 years old. They tested her for asthma they did blood work on her and found nothing wrong and even tho she don t have asthma they prescribe her the blue and orange inhalers but no matter if she s taking them or not she still can t get ride of that nasty all night caught that leaves her drained of energy caused by lack of sleep due to this horrible caught she has.The pediatrician also told me to start giving her vitamin C and vitamin D3 400 IU and after a year of taking them still no difference.We have minimal problems in the day but horrific caughing all night long so bad it makes her vomit. We also had allergy test done on her and she has no alergies. I like to try and help her with giving her lemon water to drink at night and I give her saline water droplets up her nose to keep her sinuses clean daily I also give her organic honey to help sooth her throat from the cought and a humidifier in her room at night and I elevate her with5 pillows in her bed to try and help her breath better and still no success. I m trying everything I possible can think of to help her but as the years go by she just keeps getting worse. If you have any suggestions for me or think of any test we could possible get done on her to help me understand y my little baby doll is always so sick with this horrific cough I would truly appreciate any help I can get. Feel so helpless seeing her this way and not being able to help her or even know Y she is this way. This is from a truly concerned and worried Mom. I seen this site and though maybe just maybe I could find answers to her problem on here.
