First u can avoid excess water intake and juice or Pepsi intake after 7 pm. 2nd: make sure she goes to washroom before sleeping. 3rd: keep an alarm of 1 am and wake her up again and make sure show goes to washroom and pass urine. This way if u do for some time then your problem can be rectified. You should also can get a urine routine examination done for your daughter just to rule out any urinary tract infection. There r some medicines also which are used in bed wetting but they r to be used at last. First try this therapy. And make sure u don’t scold or frighten the child. Give him or her lot of motivational therapy and give her stars and good stuff if she doensot pass urine at any night. Basically ENCOURAGE her.
