Parent, Child & Practitioner Feedback

"My son who is four was having accidents in the day this was very draining as I was continuously washing clothes and there were many times he was sent home from school. Rachel helped us over a three-week period and with her help I was able to teach him to use the toilet. He is now dry every day!"

"Rachel provided very useful and practical advice I can implement with all of my foster children and any new children I care for."
