L.; you do it with time and patience, i have 3 boys, and every one of them did not get that poopy control, until they each were 4, so be patient, and when he poops just say good boy , not lets go in the bathroom and take care of it, and sometimes i would drop their drawers and set them on the toilet and wipe thier little butts while on the toilet, to clean them, it just takes time and patience, they say there is two things we cant control with a child, thats what goes in, and what comes out, dont worry about it, seems like hes right on track, it takes em a while, continue to be a great mom full of patience, hahaahah we wait four years for them to the hang of it, and sometimes our men that are in our lives still cant pick up their dirty underwear from off the floor, just continue what you are doing and enjoy life, D. s
