My 4 month old just developed a horrible cough today. She coughs in her sleep, I'm surprised she hasn't woken up from it yet! Sounds like some flem in her throat, and she had a bit of a runny nose. If it gets worse ill go to the dr, but in the mean time, im not sure what to do. What did you do, give them any meds or just let it run its course & pray it improves? Thanks!
