Our 2.5 year old started potty training shortly before her 2nd birthday in September and we finally reached a point about 3 months ago where we felt she was daytime potty trained. She's had no issues or accidents in the past few months using all sorts of potties at home and out for either #1 or #2. This week for seemingly no reason, she's reverted back. Today, in particular, was bad. She had 5 accidents. Is this just a normal bump in the potty training road or should we be going back to Potty Bell 101?
