My older son, almost 3, has been potty trained for about 3 weeks now. One week ago I started potty training my younger son, age 2. Since that time my older son seems to be regressing while watching the difficulty going on with the younger son. He is mimicking the behavior and each day I'm backpedaling with him and I'm afraid I'm going to end up at square one soon. He doesn't initiate trips to the potty anymore and I've gone back to using the bell but not much the gate because I need it for the other son. I'm on my own until my husband returns from a business trip one week from now. I hadn't anticipated this regression and could use some advise on how to get him back on track.
