[smiley=colhello.gif] Vonni,
I totally know what you are going through. My daughter is now 12 years old but has had P for many many years, on her scalp, neck, arms and back. More recently it has travelled down her body and she has some on her legs.
We have tried all sugestions given no matter how wierd or wonderful, The only thing that really calmed her when she was little was oats, Put some porridge oats in a sock or stocking and put it under a the tap while you run her bath. This does not take the P away but it makes it less angry and itchy. I find this a godsend at bedtime.
I hope we catch each other on line sometime.
