Bed Wetting
One of the most effective ways I know of ridding children of the bedwetting problem is using an "enuresis alarm." Malem makes several. On my kids, I used one called "DryTime." I now Dr. Brazelton voiced reservations recently about it causing children to feel helpless, but what's mroe helpless than waking up in a puddle of your own urine....seriously! ANd it's certainly safer than DDAVP nasal drops which requires regular electrolyte monitoring, doctor visits, etc.
These alarms go off the moment the sensor picks up a drop of water. They are very annoying and are sure to awaken the child, but just in case, it's a good idea to have him or her sleep on a cot/mat next to your bed so you can make sure he/she goes to the bathroom to empty his/her bladder. After a few days, he/she can return to his/her own room. Within a couple of weeks, you can toss those pullups.
