So i got a cold out of the blue and my son (firat child) who is 3 month got a cold too. Mine took three days...just the sniffles and soar throat. My boy has boogies stuck in his noise...clear and ive been getting it out with a suction ball...hes had it for 1 and a half days...no fever... I guess he may have loss of appetite...he normally eats 30 oz in a day today he only eat 18 oz...i have been giving him tyneol which seemed to help his sniffles for awhile. But the 18 oz i am guessing could be because of the tyneol making him sleepy.was wondering how long this will last and when he should see a doc...again he has no fever.
