I use Fairy detergent and softener. We've had all sorts from the doctor but the best doctor advice so far is moving the LO to 1 or 2 washes a week as bathing dries out the skin. Hope it helps!
my lgs skin was extremely bad, dry, flaky, red and inflamed. I started doing oat baths every night (aldi porridge oats), using aveeno oat body and hair wash in the bath and the child’s farm oatderma cream and it has cleared up in under a week, she still has slight dry patches on her arms and legs but I’m certain they’ll go soon with our new routine. I also use fairy non bio pods and the original fairy fabric softener xx
I started using Ecover detergent and it seems to have helped.
