Alternative Remedy

>матраци week ancient is congested, has minor coughing and had a fever. i took her to her pediatrician and unfortunately her solution was to have us admitted to the hospital. they ran all kinds of tests and came up with nothing. im pretty sure the illness is just your run of the mill common cold virus, because my 2 year ancient has the same symptoms and is still romping around like nothing is incorrect with her. anyway, i don’t want to call my daughter’s dr. again, so does anyone have any advice on how i can help to relieve her symptoms, primarily her congestion?? thanks!
I don’t applaud my doctor for doing that. i reckon those tests are unnecessary. I’m sure my child isnt the first infant in the history of mankind to have a fever. this is why i have questioned this question in the “alternative medicine” category.
