Hi, theres loads of kids at this age who arn't dry, my 7 year old has been for years and was the quickest of my 3, but will still have an "accident" if she is really tired, have drank lots of coke and not gone to the toilet. My son (whose now 15) was worse, I remember letting the scout leader know that he might have an accident at camp. Some kids sleep deeper, their bladders take longer to mature, or what they drink irritates the bladder, as in caffiene in coke. Don't restrict fluids before bed, this isn't the answer, it's the kind of fluid, and I had a routine of toilet, teeth, toilet or "wees & teeth & wees again" which helped. The biggest thing however was milk consumption. Cows milk (which my son loved and my 7 year old doesn't) can cause bed wetting. Google it. Good luck, I agree with the not telling parents thing! To P**s some parents off years ago, I gave my 5 year old a Thomas Hardy novel to walk through the playground reading (not that she noticed) but lots of mothers did! lol
