thanks for choosing health care magic.Dear Sunil,see chicken pox
rashes do not stay for months,it has be something else.In kids and babies contact dermatitis
is common,in which due to some contact allergy
they get rashes on body.Some viral infections also lead to this.You should look for some cosmetic allergy
also ,and if you are applying any thing in routine or for massage you should stop that and wait for couple of days.then if this does not help you need to take her to your doctor for examination and treatment.
