question: My almost 3yr old has only been urinating in her night time diaper. She wears underwear during the day and has been going on the potty fine for over a month. But for the past 2 days, she hasnt gone at all during the day. She also had a stomach virus 2 days ago, and we have a new baby that is a month old. Could one of these be the reason, or should I be worried?
