my son did the same thing when he was 3 months old. they told me to use a humidifier in his room, and if u want u can get baby nose spray and suck the boogers out. but dont freak out with my baby he was starting to teeth, it makes them spit more and yes they choke on their saliva. if u want to check if he is wash your hands and feel his gums if u feel bumps on them then hes starting to teeth. and yes the dr. wont do much without a fever but u can go in to get their advice believe me i did. just remember you are his mom you have the right to bring him in if u want to.View Thread
