One of the standout features of these potty chairs is their versatility. As the name suggests, a 3-in-1 potty chair can serve three different purposes. First, it functions as a standalone potty. Once your child has mastered that stage, it can be transformed into a removable potty seat that fits on a regular toilet. This transition can help children get used to the concept of using a 'big kid' toilet, fostering independence and confidence. Lastly, many models feature a sturdy, stable stool that helps your child reach the toilet or sink when they are ready for the next steps in their personal hygiene routine.
