When my youngest son was a baby he developed an itchy red scaly rash primarily on his face and scalp. It was clearly visible in all his baby pictures. In some areas the skin was "weeping" which means that he had scratched his skin so much that there was infection of wet and oozing pus filled blisters. The skin would turn a crusty golden color as it scabbed. If you have an infant or child who has eczema or atopic dermatitis you can empathize with how difficult this skin condition can be for the child and for the parent. Needless to say, my son had much trouble calming himself and getting to sleep with all that itching going on. When we went to the doctor he gave us the following recommendations: Bathe him much less frequently, buy a humidifier for the winter months, use the gentlest type of soap for sensitive skin -free of allergens or perfumes, cut his fingernails so he cannot scratch, and use hydrocortisone cream for his itchy patches.
While these recommendations helped some, my son's eczema continued into his toddler and childhood years. One thing we had not known when my son was a baby was that sometimes food allergies and intolerances can aggravate eczema. First we discovered that our son was allergic to dairy and replaced cow's milk with soy milk. Then we found that he had an intolerance to soy and ended up giving him rice milk which he continues to drink today as a teen. Physical symptoms such as his eczema and chronic loose green stools prompted us to seek help from an allergist who did the skin prick test on my son. I watched as multiple welts formed on his back (a sign of possible allergy or food intolerance). In addition to having anaphylaxis to peanuts (we found this out earlier) he had a reaction to dairy, soy, and wheat. My son also has autism and we kept hearing about the gluten casein free diet for children on the autism spectrum. I finally implemented this diet for my son especially after we got the allergist's report.
After implementation of a diet which eliminated the foods which caused a reaction from the skin prick test, my son's eczema began to clear up. I wish I could say that it has totally disappeared but it does come back periodically especially in dry winter months or after he has taken too many showers or baths. He is especially sensitive to things like bubble bath which he loves, but causes his skin to erupt into a rash once again. In addition to maintaining his special diet, we do pretty much the same types of preventive measures now that we had done when he was much younger. We limit his time in the shower or bath, he doesn't use very hot water which can dry out the skin, he uses a gentle soap, he uses a moisturizer right out of the shower, wears non-scratchy clothing (nothing wool), and uses hydrocortisone cream to help control the itching when his eczema flares up.
The thing I wish to point out is that every child's eczema is different with different triggers for what makes it worse. If you suspect that your infant or child has eczema it is your best bet to ask your child's pediatrician for guidance. Your child's doctor is going to know best how to treat your child's eczema.
