I was really consistent when it comes to taking him. I did every hour or two until he made a pee or poop and keep doing that. As for poops, my son is pretty predictable when it comes to poops, usually about 15 to 30 minutes after eating and mid morning. I would take him to sit on the potty around his poop time and have him sit for 5 minutes and do that every 15 minutes or so and sooner or later he had to poop and did so. It took a few days but eventually it worked. I also constantly reminded him he was wearing underpants and he couldn't go potty in them. It took a good 3 weeks to a month before he was pretty much accident free.
