My 3 y.o. with PDD-NOS is fully potty trained for urine, stool and overnight and has been for almost a year. (YAY for that!!) Recently, he has developed severe anxiety about going to the bathroom. He will not go in alone. Unless someone stands in the door to the bathroom, he literally will be stuck and can't go. We have tried to make him go on his own and he will pace in the hallway outside the bathroom until he has an accident. Someone has to stay in the bathroom with him until he has completed and is ready to exit the bathroom.
He worries about the toilet overflowing, but that has not happened to him in almost a year. He also worries about his little brother coming into the bathroom. We thought maybe it was the combination of these two things that are paralyzing him, but I had a meeting with his lead therapist at his day treatment clinic and she said they are seeing the same thing in that setting. She mentioned that at first she just thought it may be an attention seeking behavior, but after trying some extinction methods, agrees that it is true anxiety about the bathroom.
Does anyone have suggestions for helping him with this? Seeing such a high level of anxiety in such a little guy is just heartbreaking.
