I noticed some rashes on my 4-year-old daughter's legs last week.

If your child is not complaining of itching or pain and has no other symptoms such as fever, you have done well by applying a moisturizing cream. It is recommended to use a fragrance-free product and apply it as often as needed. After bathing, gently pat the skin to leave a thin layer of moisture before applying the moisturizing cream. These measures are usually sufficient, but if the lesions persist for more than 7 days without improvement, it is advisable to consult a doctor.
