About the Wet-Stop 3+ Bedwetting Alarm The "Wet-Stop 3+" has been a globally trusted bedwetting alarm since its launch in 1979. Designed by a pediatric urologist, it is highly regarded by doctors and medical professionals. It's very simple to use. When worn correctly, the alarm sounds when a child urinates during sleep, helping them naturally develop the habit of going to the toilet. Even if a child is sleeping deeply and might not notice, the alarm alerts parents, providing peace of mind. This alarm is also helpful for children with autism and those who have difficulty noticing bedwetting or incontinence. In care settings, it allows for quick responses, contributing to cleanliness and health maintenance, and reducing the burden of care. *Batteries are not included; two AAA batteries are required for use.
