I waited a few days before leaving my comment. To be honest, I was skeptical about the effectiveness of this watch. My son is almost 8 years has a very deep sleep and never woke to use the bathroom. Result, he was still in diapers or he wet his bed several times ... 3 nights - I write three good !!! - He took the habit of getting up itself before the alarm is triggered, so even before the first drops. Three weeks later, he does not even need to get up and spend a night without WITHOUT LAYER watch with a peaceful sleep and pride peacock morning.
I would not recommend this show before the age of 6 years, since the alarm is very strong and it is very premieères violate both the child ...
