LO has been congested for a couple days now. But I haven't been too worried about it because he is stuffed up, but not runny nose or fever. Every now and then (maybe 2x a day?) he'll cough, it's like he's trying to get mucus out of his throat. I also heard in his chest when he breathes it sounds kinda "phlegm-y" or something. So I'm wondering if anyone else has dealt with this and if will just get better on it's own or if I should bring him to the Dr. WWYD?
