Potty training regression is a common setback that occurs when a child who has been successfully potty trained starts having accidents again. It can be frustrating for both parents and children, but it is important to understand that it is a normal part of the potty training process. Factors such as stress, changes in routine, and illness can all contribute to regression. To help your child overcome this setback, it is important to remain patient and supportive, and to provide gentle reminders and positive reinforcement. With time and consistency, most children will successfully navigate through potty training regression and continue to develop their independence and confidence in using the bathroom.
