My fully potty trained child has all of the sudden started peeing on the floor in his room! He peed in his toy box too. He only does this at nap and at bed time. We take him to the bathroom before he lays down and he goes every time. He also gets up several times to go into the bathroom and goes every time. Lately though he has been peeing on the floor/toy box in between going to the bathroom. I am frustrated but I am also worried. He urinates a lot! Am I overreacting or should I call the dr?
