Should a 6-yo girl still need "assistance" from her mother to clean herself after pooping?

My girlfriend's daughter requires "assistance" to clean herself EVERY time she poops at home. That seems odd to me. Without question, her mom would go in and clean it for her. I understand that every once in a while help may be needed, but I'm thinking what the heck! If she can't clean herself at home, then what's she doing when she's in school/camp? After suggesting to my girlfriend that she begin to teach rather than do it for her... 3 months later... nope... still going in and wiping her girls butt... 6 and a half years old! Is that normal for girls? I think it's really odd.
