I have a son currently 2 1/2 who is just starting to take interest in potty training. I haven't really pushed anything. I did get him a potty chair when he went from tryign to pull toilet paper off and decorate the house with it to pulling toilet paper off and putting it in the toilet. I even took his diaper off and had him sit on it once or twice. He didn't seem interested in going in it at all. He loved to sit on it in his clothes though...He thought that was great fun! I had his daycare tell me since around september or october that he is holding his urine. They wanted me to try, but i refused because i knew he wasn't ready. I just figured he would tell me when he was ready. Eventually, the potty chair got put in the bathroom and where he could not get it, but could touch it and point to it because it was being used as a stool. I have the added trouble that my son cannot really talk much yet. He goes to a daycare where they speak Korean. I love that he is learning a second language, but when children learn more than one language, it takes them a while to sort out which sounds and words go where and who understands what.
I eventually took my son to Target and we picked out a potty ring together. He loves to try to do everything that we do, so i began to wonder if a different type of seat might help. I held up one that was plain white (just like mommy and daddy's) and the only one that had "boy colors" (was blue as opposed to Pink). He grabbed the blue one right out of my hand and threw it in the cart. When we got home I took it out of the package, told him what it was for, placed it in the bathroom ontop of the potty chair, showed him where it was and left it at that. I never made him sit on it at all. I just figured that somehow or other, that he would tell me when he was ready. I think they started trying to train him at school middle of november...About a month ago, they told me that he would stand there like the other kids, but just wouldn't do anything (promise!) and on December 24th, I got a surprising christmas present. My son went into the bathroom, grabbed his potty ring and brought it to me. We went in immediately and he sat on it and had his first successful attempt at the potty. He has had lots of unsuccessful ones since then, but I went through 2 different potty chairs and a ring before he found something he liked. Also, most rings and chairs come with those splash guards...I read somewhere that using those things is one of the worst things you can do...for one thing, your son will be more interested in "sinking cherios" or aiming at different things that it won't be needed and the other is that if he hurts himself on it while trying to sit on the pot, it will delay training for quite a while. Good luck to you!
