i don't think a cold comes with a fever. a fever is a sign that the body is fighting an infection. as we have mentioned before, it can be viral or bacteria. if LO has a fever & under 1 year old. i suggest you bring him to see your ped, to be on the safe side.
my LO had low grade fever when she was 9mths. but it was like 38C, and she was only whining a bit. i did bring her to see my homeopath, and she got better with the remedies. what i did when LO was under 1 year, i always brought her to the ped to check after or during a cold/cough. I was paranoid of chest/ear infection.
there's this thing (bought from Eugene) that suck out the mucus from bb's nose. not the bulb suck, but a tube thing with a suck on one side & a collection area in the middle. i never used it though, cos my LO would struggle so much if we put sth in her nose. i did try saline nasal spray, which helped a little bit. also raised the mattress, so LO was sleeping on a slight slope. humdifying the room also helped.
