I swear by this!! My doctor gave it to me last year and as soon as I started giving it to my daughter, she stopped getting a runny nose. There are two different doses, 400 IU and 2000 IU, at the recommendation of my doctor, I give my 3 year old 800 IU's per day and my 1 year old 400 IU's per day. You have to be careful because excess Vitamin D can cause health problems, so I would recommend consulting your pediatrician before giving it to your kids, but seriously consider this for yourself and your kids!
