My DD has been potty trained for 2 months now. I potty trained her with no struggle and she picked it up within a day. She hasn't had any accidents since the first 3 days of potty training. However this week she has started saying she needs to go potty constantly, like every 5 minutes. I obviously take her however she doesn't pee or poop. Could there be something wrong or do you think she just developed some fascinations with the word potty??
