I purchased TheraPee for my 8 year old son, who is a very deep sleeper and had never had a dry night in his life. Yes, you read that right. Ever. Our pediatrician actually mentioned this device to us at his annual check-up, and although she had in previous years told us he would outgrow it eventually, told us that another patient's mother told her about this and it worked for them. I didn't think too much of it, but when we left her office my son begged to try it. I spent the money (my gut telling me it wasn't going to work) as my son was SO ready to quit wearing pull-ups. I slept in the bed with my son for the first week. The first 3 days I will admit were...well, rough. Up 2 - 3 times per night. We did have one dry night the first week. The second week we had 3 dry nights. By the 3rd week, he was dry pretty much every day (and I was in shock!). We are now finishing up the treatment 14 weeks later. He has been dry every night for 9 weeks now. This whole process has given him confidence and a sense of accomplishment. I highly recommend this product to anyone considering it. It has definitely changed our life!!! I would give it 10 stars if I could!!!
