I use to do two weeks ~ and in most cases I let up with containment unit if they are doing really well and not needing to be 'reminded' .... but I want the option for longer cause with some kids they 'seem' trained but it is only because you are in that training mode and you are reminding them the minute you let YOUR guard down and do not remind them to go they pee all over your carpet cause they themselves were not 'trained' it was just that you had been doing all the work for them with the reminding so to speak![]()
