Hives
Quick Answer
Hives are raised, red or skin-colored welts that appear suddenly on the skin, often causing intense itching — they occur when the body releases histamine in response to a trigger.
What Do Hives (Raised Red Welts on Skin) Look Like on a Child?
- Raised, red or pinkish welts of varying sizes that appear suddenly
- The welts may have a pale center with a red border
- Each individual welt typically fades within 24 hours, but new ones may appear in different locations
- The rash is usually intensely itchy
- Hives may appear anywhere on the body and may move around
- Common triggers include viral infections, certain foods, medications, or insect stings — though in many cases no trigger is identified
Why Do Hives or Raised Red Welts on My Baby's Skin Matter?
- Hives alone (urticaria) are typically uncomfortable but not dangerous in an otherwise well child
- Hives that appear alongside swelling of the lips, tongue, or face, breathing difficulty, or vomiting may be associated with a more serious allergic reaction called anaphylaxis
- The combination of what the rash looks like and how the child is behaving together determines whether prompt evaluation is appropriate

When Should I Be Worried About Hives or Raised Red Welts on My Child?
These are visual patterns that may deserve closer attention. This is for education only — not a diagnostic guide.
- Swelling of the lips, tongue, or face alongside hives
- Difficulty breathing, coughing, or throat tightness
- Vomiting, drooling, or difficulty swallowing alongside hives
- The child appearing pale, limp, or unusually quiet
- Hives that appeared immediately after taking a new medication or eating a new food
Hives accompanied by swelling of the face, lips, or tongue — or alongside breathing difficulty, vomiting, or a child who seems very unwell — are among the signs many parents bring to immediate medical attention.
