It is difficult to make a recommendation without examining your daughter. In general, cradle cap, which is also known as seborrheic dermatitis, occurs on the scalp, at the hairline, in the eyebrows, and in certain skin areas such as the creases behind the ears and on the sides of the nose. It is common in infants, usually improves by 1 year of age, and tends not to recur until the time of puberty. Seborrheic dermatitis is generally quite easy to treat. There are many other rashes that could occur on the sides of the face or cheeks, many of them treatable. I would first try some over-the-counter hydrocortisone (0.5 or 1%) cream and a thick moisturizer, each applied twice daily. Try to avoid any harsh scrubbing, which may contribute to further skin irritation. If this is ineffective, you might consider having your daughter evaluated by a dermatologist for an examination and treatment suggestions.
