Hives in a toddler can last for a few hours or a few days and are common but not contagious. Hives show up as welt-like, red patches of different shapes and sizes. They are extremely itchy and can appear, disappear, and reappear within hours.
Hives will show up when your child’s body releases histamine. Discovering the cause of hives can sometimes be impossible as histamine is released for so many reasons. An insect bite, an ingredient in food, an airborne allergen, certain illnesses, environmental temperatures, and medications can all cause a child to break out in hives.
If your toddler has hives, you should give them a bath to rid the body of any potential allergens. Then use cool compresses to provide relief to the area that is affected.
Calamine lotion dabbed on the hives with a sterile cotton ball will also provide relief to your child’s itchy skin.
Antihistamines are sometimes helpful in children with hives, although you should check with your child’s doctor to find out the recommended dosage.
In all cases of hives, watch for severe respiratory symptoms like shortness of breath, and swelling in the face, particularly swelling of the tongue. This indicates a serious condition (anaphylactic shock) and your child must receive medical treatment right away.
