Kathleen,
I must say that after I posted the query on the blisters and included
the word "addicted", I regretted doing so, it was to late.  I
realized that I should definately have been careful about the way I
worded the query.  In actual fact it wasn't even really my words, but
the words of the Child Health Nurse that referred the client to me.
I will definately watch my language, your comments were very valid.

I will consider the possiblity that the Mum has thrush, I wasn't
aware that she could have blisters, shooting pain and no other
symptoms and that it be thrush, you live and learn.

Many thanks for your comments.
Val
