How should I treat the red, irritated skin folds around my 5-month-old's neck?
Your daughter has intertrigo,
which is very common in chubby babies. Intertrigo occurs when moisture develops between the skin folds, causing redness and occasional weeping or oozing. Keeping these areas clean and dry, as you are doing, is usually helpful. Sometimes, the application of a low strength steroid cream or ointment (such as hydrocortisone) can be useful. Application of a topical antifungal cream may also be helpful, as Candida (a yeast) is often present. If there is oozing or weeping, then secondary infection with bacteria may be present and an oral antibiotic may be necessary. Avoid putting powder on the areas, which tends to clump and may be more irritating. And keep in mind that the majority of babies outgrow this tendency with aging, as baby
rolls diminish and muscle mass increases.
