My 6-month-old son has patches, sometimes down to the flesh, without any apparent cause. What can I do to relieve/improve his situation?

To help relieve your son's skin condition, you can use creams recommended for eczema, such as Aveeno, as often as needed during the day. You can also try using a thicker product like Aquaphor if Aveeno is not enough. Avoid using scented soaps during bath time, gently pat the skin dry, and apply moisturizer immediately after. Always protect his skin with a hat and scarf, even for short trips. If these measures do not improve the condition, it may be necessary to consult for a more thorough evaluation of his needs.
