Stunna, I'll try to help. If you have typical "cold" symptoms, then rest, lots of fluids and nasal saline rinses are your friend. You can either buy saline or mix a half-teaspoon of salt with a cup of warm water and irrigate the fire out of our nostrils. Afrin, 2-3 squirts, each nostril, twice a day for 3-5 days might help your head congestion.
OTC cold remedies, plain and simple, do not do much. The most complete scientific studies I've seen show maybe a 6% reduction in symptoms -- nothing you'll notice. SO, I'd save the cash and go simple.
A side note: a recent study showed Buckwheat honey superior to placebo (and dextromethorphan, or "DM") in relieving cough in children, so it won't hurt to give it a try -- although, children below the age of 1 should avoid any type of honey due to risks of botulism. No dose was specified, but I'd try a couple of teaspoons in a warm drink before bedtime.
Also, if your symptoms persist beyond the typical 7 days, or if things worsen, consider seeing your doctor. Even typical viral infections can lead to sinusitis, which might need an antibiotic.
Hope this helps, and let me know if you need further advice.
