My 5mo DS has started to develop really bad eczema all over his body. It started just on his face but now it's all over his torso, back, arms and even legs. I am off to the GP later in the week and am wondering if they will suggest something in my diet is causing it? I use sensitive washing powder, keep him cool and mostly cotton clothing etc but its not helping. He didnt have it as a newborn it's really just developed this past month so I'm a bit confused. Theres no family history either side. Thanks in advance for any advice!
