I'll just share my story to make you feel a little better...
dd (my first) just before she turned 2yo, jumped on the toilet and stated she would use it, we had the "underwear fairy" come and visit (my mom dressed up) and bring underwear and a huge sticker chart, and take her diapers away (I used cloth), and that was pretty much it. I really had nothing to do with it. DD was done, except for nighttime, which wasn't 100% till about 5yo. She wore pull ups at night, and she only peed once every few months overnight, but we had a family bed, so I liked the pull ups so everyone wasn't disturbed if she peed and I would have needed to clean up in the middle of the night. If dd had been in her own little bed, I would have had her in underwear w/ mattress protectors from probably 3yo.
Then comes ds, who at 16 months old shows me all the time how he can hold his pee in, and pee in the toilet when he wants to, start it and stop it, etc, and can and will sometimes poop in the toilet when he wants to (key words... WANTS TO). Silly me thought "oh good, he'll be around 2yo too".

(that's not me laughing, that's God laughing
at me).
Fast forward to 3 3/4yo - ds is FINALLY trained! My goodness, that had to be the l-o-n-g-e-s-t potty training period in the history of the world! 2 full years!!! I kid you not! I tried every single thing I ever read or heard (except my mil saying if it were her, she'd spank him when he had an accident

) Anyway, cloth diapers, pampers, pull ups, naked, underwear, NOTHING worked with my ds. Every reward, every chart, every cheerio-in-the-toilet-trick, ignoring it, clapping when he did good... I could go on and on and on and on! He had the body/mind connection and muscle control very early - he just wasn't going to do it all the time, and that was that!
SO, I have no advice on "how" to potty train, but I do want to share something I've recently discovered... I've been reading Dr. Phil's book "Family First", and in it there's a part on what type of parenting style each person has (permissive, equalitarian and authoritarian), and what type of personality each of your children have (passive, cooperative and rebellious), and what works well w/ each other, and what to do when you have clashing types. My dd is cooperative, and ds is rebellious. NOTHING was going to work w/ rebellious ds, while many things probably would have worked w/ cooperative dd. DS was going to do this on his own terms, no matter what. I could have given him a trip to disney as a reward, and it wouldn't have worked. DS is now 6 (soon to be 7), and I'm so glad I finally realize all this. I was just talking to dh about this today, and how giving ds more 'room' than we give dd is a good thing for everyone in our family. DS 'needs' to make his own mistakes, pretty much 100% of the time, and we'll just be there in the background to help him when he falls. DD often asks for instruction and really listens and tries to impliment what she's been told, and that works for her really well. DS shuts down, ignores, gets angry, etc, when we try to give him instructions. Of course, there are some things you can't bend on, like learning to ride his new 4-wheeler... he has to listen or he can't ride it. But on things that aren't major safety issues, giving ds space is his best teacher. And thinking back on all of ds's milestones, accomplishments, and just day to day living, this is how he's always worked best and accomplished the most. He taught himself how to swim because I put him in one of those floats-built-in-the-swimsuit spiderman bathingsuits, and set him free in the pool. With dd, we and an instructor held her and taught her, she listened and learned well. So if dh and myself become more "permissive" in our parenting style w/ ds, he'll function better, learn more, be more agreeable (I'm equalitarian, so I'm half way there anyway - dh is more authoritarian, so he's got a lot of tongue-biting to do). My mom was permissive, and that worked very well for me growing up. And permissive doesn't mean wishy-washy in any way... it means allowing the child more freedom w/in wider boundries you set, being accepting and supportive. But if I gave dd this much freedom, she'd probably flounder around a bit, instead of imbracing it like ds does. Even last night, as I put ds to bed, he told me he wants to make a behavior chart for himself, and he'll put a star for a good day, and an X for a bad day, then put himself in a time out if he has too many X's. I said "you can just put stars and not put X's if you want" (thinking about all the parenting advice i read on focusing on the good and more or less ignoring the bad), but he said "nope! I'll put X's if I've made a bad day, and I'll have a 2 hour time out in my room" (we'll see how that holds up - LOL). But the point is, dd would enjoy us doing a chart together, while ds wants me to have nothing to do with it. He's in charge! And what's funny is, mil (the potty training spanker - authoritarian all the way) and ds have ALWAYS butted heads, from when ds was a young toddler. Dr. Phil says this dyad is the most frustrating one to deal with, and I've seen it for years, but never knew why.
Sorry so long-winded... I just thought it's all so interesting and true and it's already helped me w/ ds in just day to day living and understanding him more. And if it helps anyone w/ potty training, that's great!
