Gerd aka acid reflux

Hi all I'm hoping some mommy's can give me advice on this. I recently took my 7 week old baby to doctor's because she was suffering from a terrible cough n sounded congested. Well doctor said she wasn't sick everything was ok I was left with no answers on why she was coughing after her having a dry terrible cough n spitting up yellow mucus this morning I did some research and gerd came up. I also watched videos and I'm sure this is what she has she shows symptoms of it and sounds like the children that I saw on the video. Next apt which is in a week I'm definitely going to point this out. Any mom's going through the same thing?
