Thanks Mayaness, I am going to try to get my hands on Ingrid Bauer's book.

I still haven't been able to catch a wee. No signs that I can see, maybe the book will help. DS hasn't had a pooey nappy in ages now, except last night. I don't know how I missed it, and I just felt so awful that I had let him sit in his own poo without knowing. Going to do a search for that book right now
