Switch to a perfume free detergent, try different fabric softeners or eliminate softeners. Treat baby's clothing and bedding to an extra rinse to remove excess solvents. If the irritation occurs in other areas, such as baby's face, as well as other areas of the body, the method of bathing could be the culprit. Switch to a mild, perfume free soap, use cooler bath water, and make sure to moisturize the skin while still damp. A common misconception about lotions is that they can rehydrate skin.
Lotions work by sealing in moisture that is already present.
If the skin is dry when lotion is applied, it will prevent the skin from becoming drier, but it won't add moisture. Again, a perfume free product designed for sensitive skin works best. If the irritation continues or worsens despite all efforts, an allergy may be the culprit. A trip to the pediatrician is in order. Maintaining healthy skin for babies with sensitive skin requires consistency.
