Eczema is nasty, I really feel for you, and of course your little one.
Keeping the house cool especially in the bedrooms during the night helps prevent the Eczema from itching, it is usually at night the scratching starts without you being aware you are scratching.
During the summer keep the windows open for fresh air to cool the rooms down and when it is very hot try using a cooling fan during the night. Do not use thick duvet covers during the heat, thin cotton sheets are best.
Remember to keep the skin moist at all time, even if it means moisturising four times a day, this is very important to stop eczema itching. If you have very dry skin you can moisturise before you bath and straight after the bath.
Applying vitamin E oil directly on the area affected by eczema stops itching and promotes quick healing. Evening primrose oil is an excellent remedy for eczema.
Babies sometimes develop eczema as an allergic response to everyday products like detergents and certain kinds of fabric. Avoid dressing your child in synthetics or even wool and polyester. Loose, cotton clothing is ideal for relief from eczema and other minor skin irritations. Try to use pure soap for your laundry and for baths to see if it helps the eczema diminish.
