Many different types of rashes can affect children. A child can develop dermatitis or develop a rash due to a virus, bacteria, or fungus. Although many rashes clear up quickly with home care, some require longer-term treatment or medication.
Some rashes form quickly, while others take several days to appear fully.
This article provides an overview of the most common rashes in children, including symptoms, causes, and treatments.
While most rashes are not medical emergencies, a parent or caregiver should take a child to the emergency room if they notice a rash that could indicate meningitis.
Meningitis refers to inflammation of the membranes that surround the brain and spinal cord. It usually develops due to a viral or bacterial infection. It can affect anyone but most commonly occurs in:
- babies
- young children
- adolescents
- young adults
A person may notice a rash that looks like pinpricks. These spread quickly and turn into purple blotches.
On light skin, the pinpricks are red. On Skin of Color, the rash can be less noticeable. A person can check paler areas of skin for the rash, such as:
- the palms of the hands
- the soles of the feet
- the roof of the mouth
- the stomach
- whites of the eyes
- inside of the eyelids
The rash will not disappear if a person presses a glass against the skin.
Many of these rashes are not typically a cause for concern, and a parent or caregiver can treat these rashes at home. However, if symptoms do not resolve, they should speak with a healthcare professional.
Teething rash
Teething typically starts between 4 and 7 months of age.
Teething can cause the baby to drool, and the excess saliva can irritate the skin around the mouth, cheeks, chin, neck, or chest. This causes tiny, raised, inflamed bumps to develop.
Diaper rash
Wetness and friction from a diaper can cause diaper rash to develop on or around a baby’s buttocks. This is a rash that a person can typically treat with home care.
Diaper rash can be a form of irritant contact dermatitis or result from a fungal or bacterial infection.
Symptoms of diaper rash include:
- raw patches on the buttocks in the diaper area
- skin that looks sore or is warm to the touch
- scaly, dry skin
- fussing or discomfort
- pimples or blisters on the buttocks

Around the scalp and face, an infant will develop patches of yellow or white greasy scales. These can crust and fall off.
It can sometimes affect the diaper area and appear as small, dry flakes of skin.
The scales look similar on all skin tones. However, on darker skin, the skin underneath the scales may appear darker than the surrounding skin. On lighter skin, the skin will appear red or pink.
