What causes rash on baby that looks like ant bites but comes and goes in different areas?

Answer 1

The rashes that looks like ant bite are hives.

Hives occur when the body releases a chemical called histamine. There are so many possible reasons for hives that you may have trouble identifying the culprit. Here are the most likely ones:

Insect bites and stings. If your child is allergic to bees or fire ants, for example, he could develop hives in reaction to being stung or bitten.

• Food. Your child might get hives in reaction to something he eats. The most likely foods to offend are milk, eggs, peanuts, tree nuts (e.g., almonds, walnuts, pecans), soybeans, wheat, fish, and shellfish. Certain food additives and preservatives can also trigger hives. Your child may break out in hives because he's allergic to the protein in the food, or simply because his body reacts to a chemical in the food by releasing histamine. Some children even develop hives simply from coming into contact with certain foods - for example, when the juice from a strawberry gets on their skin.
• Allergens: Children who have developed an allergy to cats may break out in hives when they touch a cat. Your child may even react with hives to an allergen in the air, like pollen.
• Illness. Your child might get hives when he has a cold or other viral infection. Less commonly, he may get hives when he has a bacterial infection.
• Temperature. Sometimes cold temperatures cause hives. The same goes for a sudden change in temperature - such as when your child's skin warms up after being cold.
• Drugs. Antibiotics and some other medications might cause your child to break out in hives.
