When you were a child, there probably were not such things as bedwetting alarms. If you were a bed-wetter or continued wetting the bed long after your parents believed you should have stopped, then you may have been subjected to a variety of embarrassing or even traumatic experiences in order to make you stop doing it.
Times have changed and now there are more effective methods to help children stop wetting the bed, one of which is a bedwetting alarm.
Most kids will wet the bed from time to time, after all that is why there are plastic mattress pads. But, there may come a time when your child appears to be too old to still be bedwetting.
There is no official cutoff point after which your child should stop wetting the bed, but most experts would say that by the age of six or seven, those days should be pretty much over. If your child continues to wet the bed either occasionally or regularly after that point, then you may want to investigate some of the potential reasons for their bedwetting.
