The Rodger progress chart is a nice and handy way to get involved with your child’s problem, by rewarding your child by sticking a thumb sticker on the calendar when the child is dry.
Using the calendar is a motivating support during the training.
The child gets the feeling that he/she does not stand alone.
The parents mark the result on the calendar. After a dry night the child may stick a sticker.

Never punish your child; your child is not reponsible for occasional accidents.
