Now that I am a mother of 2, I've discovered that kids share their illnesses like they share their toys. So far this winter, our illnesses have been so cyclical that I feel like I am being pulled into a black hole of boogers and vomit. However, due to the never ending void of illness in our house, I have had lots of practice with what works and what doesn't as far as treating my kids' symptoms. 

1. Essential oils - My husband might roll his eyes at this one, but Plant Therapy's "Sniffle Stopper" really helped my kids stop sniffling. It works kind of like a Vick's vaporub, except you can rest assured that there are no chemicals in it. I also like to diffuse lavender, eucalyptus, and immune boosting blends. Essential oils are helpful because they are plant based, so you can't over dose your kid with them, and you feel like you're continually doing some thing to help your kid. Giving medicine is great, but I would count down the minutes until I could give another dose, and I was too afraid to mix any other medicines with it. Oils definitely put my mind at ease as they can be used in addition with medicine, and it feels like I am actively taking steps to help my kids feel better. 
2. The wisdom of the Facebook moms groups introduced me to Activated Charcoal for the stomach flu. The second some one throws up, you can give it to the ill child to shorten the time of the illness, and If you take a capsule every 4 hours for 24 hours, you will most likely skip getting the flu. This is obviously helpful because being sick sucks, but also because it is way easier for you to care for sick kids if you yourself don't also have the illness. 
3. You don't want to get other kids sick or risk your own kids picking up another illness, so you don't leave the house. Possibly a good choice for your family's physical health, but for your mental health? Not good. I am increasingly irritable and even depressed if I don't leave the house for 30+ hours. Make time for yourself to go out, whether that means calling a sitter or asking your spouse to take a turn with the sick kids, you need to nurture yourself in order to have the motivation to take care of sick kids. 

Obviously I recommend Tylenol or whatever other medicine your child may need, but these are additional tips that have really helped me survive winter's cold/flu season.
