My 3 month old got extremely stuffy all of a sudden. You can hear his poor little nose when he is sleeping. I am trying to keep it clear by sucking it and using saline constantly. He doesn’t have a fever and is still eating but he just seems fussy. Should I bring him in to the doctor? Or wait it out since as long as he doesn’t have fever. FTM and this is is first time showing signs of not feeling well.
