M., My heart really goes out to you. I was SO frustrated trying to potty train my daughter, I kiddingly said "If I had a gun, I would shoot myself" (not really!)
Someone told me this: "YOU know your child better than anyone else, and YOU will figure it out". I figured that she was right. I did know my child better than anyone else. Then asked myself, what is it I know about her that I could use in trying to potty train her? The answer: She is absolutely an alpha female, is independent, likes to be in charge, likes when she thinks things are HER idea, and is a natural born leader. Simply put, she has "control issues". LOL. Well, I used THAT in reasoning with her.
I got down to her level, looked her square in the eye, and told her that I had forgotten to tell her something very important about the potty. That SHE was the "BOSS" of her pee-pee and her poo-poo, and only SHE could tell it when to stay in, and when to come out. Mommy and Daddy are not the boss of her pee & poop, ONLY she is, And that WE couldn't tell it to stay in or come out, only Briana could. She went to the potty both 1&2), by herself THAT DAY! I hope that helps!
Just remember that YOU know him, and ask yourself what do I know about him (personality-wise) that could be helpful? Here is something you said that popped out at me: "His Uncle the other day was over and asked him about the potty and sure enough he ran to it and did the motions for him. This kids is a character I tell you. I do feel when he does start it won't be training he will just know to do it. he has been like that with everything crawling, walking and even talking".
This is what I read into that statement:
He is a character! He KNOWS "what" to do! And it sounds like he may be "putting on a bit of a show", or "like to put on a show" You also said that he's been like that with everything crawling, walking even talking, so it's just "his way". Don't fight it, work WITH it!
Also, since he is a boy, simply watching another male as an example could help. (Since mine is a girl, I served as the example and left the bathroom door opened (most of the time), when I used the potty, and you really don't have to say a word, cause we all know they may not look like it, but they do watch and listen to EVERYTHING we say and do! Good luck and keep us posted on what finally works for you!
