Ah, N.,
So sorry your little one has a cold. I remember the first time my son had one; my husband was out of town, which was a good thing as most of my attention was focused on my boy.
Check in with your pediatrician regarding fever reducers, dosages and when to use it/when to let it run it's course. I think forums are fine for something, but better to get this information from someone who can be accountable and who has all the updated info.
Besides taking echinacea while I was nursing, I also propped myself up with pillows so that my son and could sleep with our heads elevated. If you use a crib, remove the mattress and either use a foam wedge (there are some specially made for this) or some tightly folded/rolled blankets to elevate one side just a couple inches. It shouldn't be so drastic that he rolls down it. Double-check to make sure that there are no gaps and that it is all very secure before laying your son down in it.
I wore my son a lot, which seemed to help. Another thing we did was to go into the bathroom a few times a day and run the shower on hot and just sit near it, on the lid of the toilet. The steam helped to break up some of the junk in his sinuses and lungs. If you can do nose drops, so much the better. (My son fought me on this, so the steam was better overall.)
The Dr Sears website has more very good information.
And as for cold meds, steer clear of them. Cold meds are for people who are forcing their bodies to function when they should be resting and healing. (Circumstances sometimes dictate these things..this isn't a judgment, just an observation.)The biggest problem with decongestants is that it dries up the mucus membranes, which function best when moist to rid the body of the virus. A runny nose is far more productive than a dried-up nose in getting us well and my experience is that cold meds actually prolong the cold as it stymies the body's natural defenses.
Take good care!
