DD is almost 3 and has been potty trained (during the day) for about 3 months. She has never had an accident (except for within the first few days of potty training). 2 times in the last few days she's had an accident. Is it normal to regress like this after 3 months? Any suggestions on how to get her back on track? i know 2 times isnt a lot, but it was just so odd.

TIA
