Both my brothers wet the bed until they hit puberty...so did my one uncle on my mom's side. And so did one of my cousins on my mom's side.
At one point my mother went to the base hospital about it because it was overwhelming her changing sheets everyday and cleaning pee soaked clothes everyday...and so on. They prescribed a medicine that did the trick....it worked so well my aunt asked her doctor about it and he prescribed it for her son.
Long story short her six year old wet his pants in school and he was so embarrassed that he decided that if one pill at night kept him from wetting the bed, then the whole bottle should work better. He snuck into the kitchen while his mom was giving his baby brother a bath and he climbed the counter and on top of the fridge to get the medicine out of the cabinet. He took the whole bottle and in the middle of the night he started to scream. He ended up in the hospital in a coma for several weeks. He didn't make it. He turned seven in the hospital and died about two weeks later.
Turns out the medicine was experimental, but not a single doctor informed my mother or my aunt of that fact. The medicine built up in the body instead of being eliminated. My brothers both had high levels in their blood stream.
A lady investigated the use of experimental drugs by the military and wrote a book about it. She dedicated that book to my cousin and our family.
Some times I think it's best to just deal with certain things in life. Here is what my mother did with my brothers:
They were in bed by 7:30 everynight so nothing to drink after 5pm.
She set her alarm for two times during the night...11pm and 3am or something like that. It took a bit to figure out what times were best. She got them up both times and took them to the bathroom. She learned she had to watch them carefully because they were so groggy they would walk into the wrong room and pee on something like the piano or in the laundry basket.
She discovered that they could only drink water at dinner time (maybe milk too, but I don't remember) No sugar drinks or juice and definitely not soda with the caffiene because it acted like a diuretic and they wet everywhere. And no watermelon at dinner time.
She put plastic covers on their mattresses. She had them help with the sheets if they had an accident.
She watched them brush their teeth at night because they would drink from the faucet...sneaky guys.
I think she did a few other things but I don't remember now.
But they both had problems until they hit puberty. One quit when he was in middle school and the other quit his freshman year in high school. If she was diligent, she didn't have to clean too much.
