Please know first of all that I "feel her pain!" My 7 year old boy can go around 7 days at a time without wetting, but then will wet several nights in a row. There was a time when he wet every night. This is kind of a long response - I hope it's helpful.
The first thing to do is consult the pediatrician to make sure there is no physical reason for her wetting. If not, just know that some kids do this and sometimes it is an inherited tendency, and the current thinking is to treat it matter of factly and not use punishment or reward - it is usually a physical maturity thing that has to do with deep sleep and the brain/bladder connection (as children grow, the pituitary gland begins to put out a hormone at night to decrease urine production).
For the daytime accidents, she can be taught with a reward system to increase awareness and going to the bathroom regularly - that is usually a different and separate issue but sometimes will help resolve the nighttime wetting, at least to some extent.
To survive this phase, I have bought several waterproof pads that cover the sheets so that worst case most days all I have to do is wash the pad and blanket and whatever else (I throw EVERYTHING in the wash including stuffed animals, yes even beanie babies). The bedwetting store online has terrific pads that my child is comfortable sleeping on (they have different sizes & I use the "tuck-ins"). They are expensive but regular stores do not have large enough pads, and their pads slide around. I have wrapped his mattress in a zipper vinyl covering (can get them at a place like Bed Bath Beyond). Then I put a regular mattress pad over that because these things can be hot for sleeping, a waterproof pad over that, then the fitted sheet. While this sounds like overkill, it saves on time and laundry depending on the extent of wetting. He also has a vinyl pillow because sometimes he wets enough to soak the pillow case. We don't use the alarms because if getting soaked doesn't wake her up, an alarm probably won't - and most of my friends did not have success with them.
My son only sleeps with a blanket for the season and as small a one as possible at that - I do not do the whole bed making hospital corner thing, WAY too frustrating.
I've taught my son, who usually wakes in the middle of the night to a soaked pad and blanket, to take the wet things off the bed himself and put them in a basket by his bed (well usually it's the floor coz we have hardwood and it's old and not recently finished so I don't care). We abandoned pull-ups when he was 5 because they didn't help at all, he'd leak right out of them and it was a waste of money.
So that's my 50 cents - good luck to you and your daughter! I know it's frustrating and I am always behind on laundry; this too shall pass.
