the title pretty much says it.
DD has been potty trained for several months now. In the past week we have had a major reversion. She won't go potty if she is in the middle of playing and has to go. Instead she holds it until she can't anymore. It started with a little bit here and there early last week. Suddenly she is having accidents at school too. Yesterday she had a MAJOR accident and I needed a mop to clean it up. She was so down about it that she went and put on a diaper herself when I told her to go put her wet clothes in the hamper. Today it happened again at Monkey Joes. I started to wonder if she had a UTI last Thursday and asked her if it hurts to pee and she says yes. But I can also ask her if her big toe hurts and she will say yes.
Is this a normal three year old thing, or should I really be worried about a UTI?
