Its totally normal and it means she is starting to be aware of her body functions. this is the first step before being able to control their body function which is needed for potty training. This is a good indicator that she is not ready to be potty trained just yet. it has nothing to do with age and everything to do with their development path (which can be a few weeks, few months, or a year). talking about it iwith her is great and that will help you be aware of when she is ready to be trained. this will save both you and her a lot of frustation. good luck!
