My oldest son is 4 1/2 and he has recently started pooping on himself. He says he doesn't know whats wrong and that he forgets. He has been potty trained for a long time now and sometimes he will do this multiple times a day for days and then go a week without pooping himself. Im currently pregnant with my third and im wondering if this is a regression type thing or if this could be psychological? Any advice or personal stories? I honestly don't know what more to do!
