K.S.
I am new to this site but read your request. I have an 11 year old boy and he still wears Goodnites because he still wets the bed. He has been through so many tests and counselors and everything is normal. He just has not grown into his bladder yet. Their bladders are so small and as everyone else told you on here, the urge doesn't wake up the heavy sleepers. He is so out of it at night he doesn't even stir. Because he is so big now, he often leaks through his pants after just peeing once. Our counselor said to give him incentives, like if he goes 1 night without peeing, small gift, 2 nights, special dinner or something they like, age appropriate of course....and so on. Sometimes it helps and sometimes it is just something we have to live with. It isn't something they do on purpose or to upset you.....they simply don't wake up. Believe me we have tried everything under the sun! He is very mature about it, he gets up, takes it off in the morning, ties it up in plastic bag, and tosses it in trash, then showers. So he does his part and we just encourage him. Limitting drinks after 8:00 is good just don't make a big deal out of it. Give them a small drink of water (a single drink) rather than a cup or bottle if they are thirsty. My three other children have no problems in this area so we were baffled.
Also, we invested in a plastic elasticized matress cover, about $6 for a twin bed, they also sell them for crib mattresses. All you have to do if an accident happens is pull off top sheet and wipe with a cloth and some lysol. Sounds more compllicated than it is. It dries quickly doesn't stain mattress and you can put a clean sheet right back on. Since my son has this problem, we don't put all the extra sheets and blankets....he only has the bottom sheet and a blanket to cover with, like a throw. We keep an extra bottom sheet and blanket on the dresser by his bed. That way in the middle of the night you don't have to go digging in the closets and such. I know this probably isn't what you wanted to hear but it isn't something you can force them to do. Hope the information was helpful and try, most importantly, to be patient.
p.s. taking her to the potty every few hours at night is exhausting to you for awhile but is very helpful in training her bladder and her to wake at those times. Try to be consistent and do it at the same time each night. It only takes 5 minutes and you can go back to bed, and BUY SOME PULLUPS!
