My two year old daughter has a rash all on her back. Do anyone of you know of an effective home remedy?

Calamine lotion works best for rashes in kids. Also try aloe vera gel. A good way to see if a rash is worth the trip to the doctor is by stretching the skin of the affected area. I read about it in Dr Spock's book of parenting and childcare. If the skin looks fine on stretching, perhaps it's a temporary thing and would go away in a couple of days. If it looks red and inflamed, rush to the doctor immediately.
