Potty training a 4.5YO girl with a lazy bladder and a urinary tract that’s meddled with surgically when she was only 13 months old is indeed tough. I have now kept Cass diaper-free during day time and only put a pad on for her. The pad is wet every half an hour. If she does not drink water, then the pad will not be wet. But if I do not feed her with lots of water, I will be paranoid of another problem – UTI attack and constipation! Tough job for me. I need divine intervention!
