Just a quick background. My fiancé and I have been together since shortly after his divorce. He has a son with his ex wife, who is 5 and I have a daughter who is 12. We recently moved in together. We have SS5 every other weekend plus Wednesday night. There is a lot more to vent in all this but the one that is driving me up a wall right now is SS5's inability to potty train. For 3 years, I've watched him pee and poop himself constantly. He knows he's doing it cause he will back up and squat in a corner of his room to do it.
