Currently training my son, and it's hit and miss. He just turned 3, but he's behind in speech so the communication isn't what it should be for his age. He'll go if you take him and sit through it with him, but he won't come let you know he has to go. Sometimes he'll tell you he has to poop, and then he'll sit there forever without going. After 10 minutes of waiting, you get him off the potty and then right afterwards he goes in his pants. I know he's close, but it's hard with the communication issue. Right now I'm working on a reward system. He gets to do his favorite thing, which is turn on a light, if he goes on the potty. Any ideas?
