My dd has been dry thru the day since 23 months. For the past 6 months never has an accident daytime. 4 months ago had a few dry nappies at night so we took the plunge and took them off at night and since then we have had 3 or 4 dry nights then 3 or 4 wet nights she never wakes up I only discover she is wet at her normal wake up time. Iv tried lifting her before I go to bed but she is still wet more or less 50% of the time. She is a very deep sleeper. I'm considering the alarm as I know she is physically capable due to number of dry nights we have had. But concerned she is too young I should add that she would understand an explanation of how the alarm works. Would value anyone's thoughts or experience with this one. Thanks.
