Ok, it's a bit out there - but I've heard cradle cap can be related to a gluten intolerance. My 2 yo and 10mth old have had it for a while (not too bad, but its been there). anyway, I noticed yesterday that it was better, and realised that we had been pretty gluten free the last couple of days (not intentionally, we just haven't had bread in house).

Something to think about...
