DD (almost 4) has been potty trained for about a year and a half and hasn't had issues. Lately she has been having several pee accidents a week and today she had a big poop accident. We haven't had any major life changes and DS is 18m so it isn't new baby regression. I'm just wondering at what point accidents become reason for concern. Her 4y checkup is in early April, should we just wait it out until then or do we need to do something now. Just curious and needing to vent.
