Potty Training Gifted Kids
In addition, because gifted kids are usually able to understand reason, their parents can make the mistake of thinking that all that is necessary to potty train a gifted child is to explain why it must be done. However, gifted children, no matter how smart they are, are still children. That means that they can be just as resistant to potty training as any other child.
This is not to say that reasoning with a three-year-old gifted child about the necessity of using the potty won't have an effect. It could. When nothing seems to work, however, the best advice is the same advice given to parents of all untrained toddlers -- wait until your child is ready.
