I have just finished reading 'The ins and outs of poop' by Thomas R.Duhamel. I noticed this book on the Eric website and also stumbled upon the website of this clinical psychologist which gives really good information. Along with the treatment recommendations from our paediatric consultant in June and having read this book I feel a lot more confident to help my daughter. She has taken movicol for over 2 years but the GP never gave information about how to try and retrain the bowel and get out of the withholding behaviour. It has taken me a long time to realise that my daughter withheld her poo as not always obvious. Now I understand that she did in the past and often tries to now. Highly recommend this book.
