DS took a long time to stay dry at night and had gone 9+ months being dry. However, the last several weeks he is wet almost every other night. It does not matter if his BS is in range or not. He is also wearing a bedwetting alarm to wake him up and train him to get up in the night to use the bathroom (this is how we trained him 9 months ago) but it does not seem to be working this time. Do I need to worry about this regression? Should I take him to the doctor?
