one question is your child on Adderol?? I am curious because those are the same problems my daughter had for the 2 years she was on adderol until we finally gave up. She tried other ADHD meds that didn't work out for one reason or another, but the biggest problem was the constipation and bed wetting. Once of the meds she has been fine every since.
You should arrange a follow-up with her pediatrician, who will place her on a regimen of laxative and stool softeners to clean out this impacted bowel. This condition is the most frequent cause of soiling in children, and it is a contributing factor to some enuresis as well. You'll only know the possible benefit re: the enuresis when she is cleaned out. Do not, however, try to do this without medical guidance. The regimen will be effective, but it's not something to pursue on your own.
