They make goodnights which are basically diapers for really big children. Talk to her about them and tell her that the overnight pads can be a secret between you 2 girls so she does not feel like a baby or ashamed. do not assume that your daughter wets the bed due to the tragic event there may be another issue. Many children sleep very deeply and their mind does not wake them to go to the bathroom. If you spoke to a doctor I think you would be surprised how "normal" it is for a child that age especially a girl to wet the bed. So what do you do...well reduce her caffeine...that has been linked to bed wetting. Talk to her about reducing the fluids she consumes 2 hours before she goes to sleep. If she is really thirsty during that time, suggest milk (it is a solid and produces less urine than water or soda). Going to the bathroom before bed is a good idea but remember it takes the body time to process the fluid she consumes so it is not going to all "come out" before bed. Go to walmart or target and purchase bed pads...these are plastic lined incontinence pads like you sat on in the hospital when you had a baby. They make them for elderly people and will collect the urine if you do not want to use the overnights. They go under the fitted sheet (part of this is plastic so you never want anything plastic near a deeply sleeping child). Most of all remember she is 10...still very much a child and this is humiliating for her. The bigger deal you make of it, the worse it will get. Treat this as no big deal by talking to her and offering suggestions and allowing her to be part of the solution.
