It's pure laziness on the parents part! If the child is wetting the bed, don't give him anything to drink at least 1 to 2 hours prior to bedtime. If that doesn't help, the PARENTS should set their alarm for every 1, 2 or 3 hours to take the child to the restroom!
The kid is humiliated enough knowing he's 10 years old and still wetting the bed. More humiliation will simply compound the problem.
