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 in a deep sleep and unlikely to notice, the alarm alerts the caregiver, providing peace of mind. This alarm is also helpful for children with autism and those who have difficulty noticing bedwetting or incontinence. In caregiving settings, it allows for quick responses, contributing to cleanliness and health maintenance, and reducing the burden of care. *Batteries are not included.
