Night time bladder control requires the combination of three separate systems. One is the production of the hormone vasopressin. Its purpose is to balance fluid levels within the body, and overnight, it causes the kidneys to reabsorb fluid so that the bladder does not overfill during times of sleep. Secondly is the stretch sensors on the bladder which informs one of the need to urinate. The third is the external bladder sphincter. A baby normally has this semi relaxed. As a result, when the bladder fills, it does not stretch before the baby urinates. When a child's bladder starts to stretch, they close the external sphincter while the internal sphincter opens. This causes the bladder to begin to stretch and the tell tale signs that they need to go to the bathroom.
If a child is reacting to these signs during the day rather than forcing themselves to urinate on your command, the bladder stretches and the child also gains night-time control. If not, there is no way the child is getting the correct signals.
In anickelstory's daughters case, it seems that the child, while asleep, completely relaxes all her muscles. I presume it is a version of neuropathy, which I suggest that it be checked out.
There is very little difference between daytime bladder control and nighttime bladder control. I am aware of secondary nocturnal enuresis - sleep wetting where the child has been previously dry, and the medical reason is due to puberty, and the shift in the nerve & muscle positions before / during and after puberty. Very few people in the world did not suffer from this in some form, but that is NOT the case with this ladies daughter.
In relation to cloth diapers, they are available up to adult sizes. I do suggest that you check out the site I linked. In relation to other diapers, check out www.saveexpress.de/, a site that supplies disposable and cloth diapers and accessories in sizes from babies to adults. Now, the disposable range that cope with a heavy wetter would be www.saveexpress.de/en/inkontinenz-einweg-disposable/windeln-pants-diapers/mydiaper/8948/mydiaper-yellow-nacht-windel-gr.m-gelb-10er-packung with capacity of 4000ml. These would retail at $2+ each plus shipping, and personally I think that they are too expensive where cloth would suffice.
I do have a 19 year old incontinent daughter with MS, so I know what I am talking about. Most of the larger disposable diapers available in retail are cheap paper junk with both Molicare and Attends among the worst. Some of the other brands are sold with the tag line 'breathable' or 'cloth covered'. These are also poor quality and leak like a sieve. As a result, I have to go to companies like Tena or Drylife for diapers in the 'Active Fit' range where they are plastic backed for an active person during the day, where cloth diapers and plastic pants cope with overnight.
it is shocking that most medical services provide the junk Molicare / Attends diapers that are, in my opinion, worse than having the person wear nothing.
