My 2.5 years old toddler has red rashes around her mouth like very dry red patches, what causes it, could it be the wind?

Could be...: While irritation from wind could be one cause or an additional irritant, in that age group peri-oral dermatitis (rash around the mouth) is most often caused by her licking around the lips and mouth. It even has a doctor name called "lip-lickers dermatitis. Sometimes moisturizers such as vaseline or lip balm put right on the skin can be helpful. Encourage her not to lick around lips.

The dry patches may indicate a contact dermatitis, often due to excessive drooling or a particular food. Cold temperatures may dry the skin and also lead to this rash. Apply an over the counter baby eczema cream after checking with your PCP. Other areas which may be affected include the hands. Watch for drainage, redness and swelling.
