My almost three year old has recently become terrified of pooping. I read the book recommended on the blog and I think we are sort of borderline into functional constipation. I have everything to really focus on this over the long weekend. The thing that's tripping me up is how to talk to him to alleviate the fear. Telling him it's not going to hurt doesn't seem to do anything when he won't even sit to try? Any advice would be greatly appreciated!
