Cradle Cap, Or other?

Stuperman Is three, going to be four at the end of June (and yes, I am still a bit bitter that he refused to wait five more days in uturo so we could share our birthdays!) It took him two and a half years before he needed his first hair cut, and that was just a trim around the ears!

Since then, like his brothers, when it comes time for a hair cut, we bring out the clippers and shave them almost bald. Seriously.

Stuperman has a bath almost every single day, but I do not wash his hair every day - unless he needs it becuase of a spaghetti or mud mishap, he gets his hair washed every second bath.

Last night he was sitting on my lap and I was rubbing his head when I felt something in his hair. when I took him to the bathroom to look - better lighting in there - it reminded me of when Rainbow man was a baby and had cradle cap. I used a brush, a comb and even my fingers to try and get this stuff off his scalp, but no go, and when I could get some off, the skin underneath was red and sore looking so I gave up.

My mother in law thinks it is cradle cap becuase I do not brush his hair regularaly ('cus DUH, he has no hair to brush!) but because Hubs is using a psoriasis treatment on his scalp, I am worried that this is something more than cradle cap!

Should I go and buy one of those wee soft baby brushes and try brushing his hair a few times a day to get rid of it, or should I pony up and make him a doctors appointment. It doesn't seem to be bugging him, and his annual physical is just a few months from now, in June.

Someone please tell me there is a point that your kids get old enough that you do not constantly have to worry about the decisions you make !~
