Hives are a very common condition in children. They present as itchy, red and white raised welts or bumps on the skin.  Hives are not contagious and they can last for a few hours to a few days, though in some acute and chronic cases, they may stay for a few weeks.  Hives appear when the body releases histamines in reaction to an allergy or even from heat, anxiety, infection or changes in temperature.  If your child has hives, there are simple ways to treat the welts either using home remedies or by getting a prescription from your child’s pediatrician.
