I regret that I just happened to see this today. How did things work out? Was your child able to move her bowels?
I have a fair amount of experience in treating children in this age group with constipation problems, and if she is continuing to have problems, I am willing to try to help.
Meanwhile, if you haven't tried a disposable Fleet Oil Enema , that may be a good place to start. Less than $2 at the pharmacy.
