Sorry if this has been posted or brought up in another thread but I'm so excited I had to share.
All three of my kids had cradle cap (known as cradle crap in our house) BAD. I've tried every trick in the book at this point, including adding a Biotin supplement to my vitamins in a last ditch effort to solve the issue nutritionally with kid #3. Little Man's crap actually got *worse*. To the point where I was embarrassed about it because he looked so crusty and gross.
I came across an article recommending Dr. Bronner's Magic Soaps and thought I'd try it. Boom! One use this afternoon and it's almost all gone. Sadly I don't have a before picture but here's an after shot! Just imagine the same head, only thick with yellowish scales and crust up past the hairline on his forehead. No scrubbing, either! Just let it sit for one minute and then lightly rubbed with his wash cloth for less than ten seconds.
Had to pass this along in case others were struggling.
