I need advice

Hi mommas,

So, my 15 MO has been sick for a few months now off and on coughing mainly at night which triggers into her throwing up. We live in the Chicago land area where this weather is so unpredictable lately. I've taken her to the Doctor and they checked her lungs and everything were clear no signs of wheezing either. They said it was something viral and runs its course.

We've tried a humidifier all night, elevating her, baby cough meds, vicks, steamy showers, etc. Any advice or ideas??
