Well, generally fungal infections are whittish coloured lesions with scaling on them and itching. But any skin lesions is better diagnosed after seeing it rather than reading about it. In any case, I would advise you to see a pediatric dermatologist
because it is progressively increasing in size and is recurrent. Even after relief for a few days, it is recurring. So, it must be a progressive dermatitis
. Does your child also have some whittish flaky skin on the scalp? Well, this and many more questions will need to be answered by you. Specially, now that the face is being involved and in infants the facial skin is very delicate, it will be better if a pediatric dermatologist sees the lesions and then treats.
Hope I have been successful in helping you reach to a conclusion and make a decision. I will be also available for any further doubts if any. Take care and stay healthy.
