I just really want to encourage you to NOT make a big deal about this. I'm telling you, the more frustrated you get, the more pressure you put on the child, the MORE the accidents will be.
I have two 11 year old children who have difficulty wetting at night. THEY HATE IT!! Frankly, I don't care about it...because I understand that there are physical, emotional, and developmental issues that can cause this. I also simply require them to take care of their own bedding and clothing. The washing machine isn't that difficult to put clothes into. When the children are little I, of course, start the machine and watch them put the laundry into it, but they gather their things for washing.
For my daughter, it's an indicator to dyslexia--you can google dyslexia symptoms--but I wouldn't worry about that particular problem at this point.
I think the advice you've gotten so far is sound. Go to a Chiropractic doctor without hesitation, and absolutely take her to a Pediatric Urologist after her regular doctor rules out a simple bladder infection.
This is COMMON. At this age, it's generally NOT do to laziness but a bladder smaller and more immature than the rest of the body.
Mainly, I want to plead with you not to make this thing be a source of ruin for your day and your daughter's. My daughter has make me understand that this is highly embarrassing, terribly stressful and painful for a child, and has gotten to the point where SHE HATES herself. Our boy tries to pretend it doesn't happen because he, himself, is also very embarrassed and doesn't want others to know. Seriously, if YOU think you hate it, put yourself in the place of your daughter who doesn't like how it feels, doesn't like disappointing you, and feels helpless...and has to go to bed thirsty.
OH, that's another thing. As doctors encourage; avoid restricting too much water. Children who wet the bed are at risk of dehydration because they or their parents try to avoid the bed wetting so the children tend to not get the full amount of daily water they need.
Anyway, I feel for you. Go out to the bed wetting store online. There's lots of good information out there.
