My son was finally trained at 3 yrs, 3 mos. He was not at all interested although he was able to do when he was so inclined. My mom called me at work one day to tell me Dr Phil's show that day was going to include a guaranteed 3 day potty training technique. I rushed home, watched the show, and over that next weekend - columbus Day weekend - which in the NY area is a 3 day weekend, that child got trained!!!
The whole idea behind it is that kids are best trained by positive reinforcement (think pavlovs dogs) not by negative when they don't do it. First you tell you child what the plan is - you need short term, middle term and long term rewards. And remember at 3 yrs old short term goal means instant (mom cheers YAY! I'm so proud of your, throws some confetti in the air and give them a few m&ms), middle term goals (after using the toilet all day we're going to have a special treat - if he loves Diego or Power Rangers then call "Diego" or his favorite "power ranger" (your DH, uncle or another family friend who can take the call with a decent impression) after he uses the toilet in exaggerated expression tell them excitedly "Guess what? 'Timmy' just used the potty!!! - it's so amazing because he did it all on his own - he told me what he was doing and he just went & used the toilet like a grown up boy! Do you wnat to talk to him?" Then hand the phone to your DS. Make sure the imposter on the other side of the phone is equally excited - "WOW that is so awesome - you used the potty all by yourself? You must be so proud of yourself - how cool is that?" etc. At the end of the weekend have a party - invite special important people - grandparents, favorite cousins, best buddy from next door. Have soda, cupcakes, more confetti. Sing "for he's a jolly good fellow" - include a few cancels - why not hey love blowin out candles at this age...
Lay it all out ofr him before the weekend (or another 3 days that you'll be home) begins. Make sure it's going to be a quiet weekend where you'll be around the whole time and won't have special company. Tell him what you expect of him - that you know he can do this becuase he's getting to be a big boy now. Tell him when he uses the potty he gets some m&ms. Make a huge deal of it (YAY!!! hugs, "I knew you could to it - I'm so proud of you"). Remind him that if he uses the potty all day we're going to call the red power ranger (or whomever) - make sure to make that call if he stays dry. If he makes a mistake don't make a big deal - almost ignore it - change him into dry stuff, no negative response - just tell him "OK - now you're dry - I know you can do this next time - you know what it feels like when you have to go. Remember you get m&ms when you use the potty." Chances are the first day he won't stay dry - not a big deal just reinforce what you already told him.
Finally when he finishes the 3 days (allow a mistake or two in the first day or two as long as he doesn't completely ignore it and shows that he tried - and the 3rd day is dry) have that promised party.
i swear it worked liek a charm for my son.
One note - some kids can not stay dry at night until they're older. My DD was in late 1st grade before she could stay dry through the night. There's a hormone that's secreted that makes the kidneys hold fluid through the night and then release it into the bladder in the morning. For some kids enough isn't secreted until puberty when all the hormones are in overdrive! So if you kid is able to be dry all during the day with out a problem but jsut cannot stay dry at night don't be rough on him - something like 10% of kids are 6 or 7 before they can stay dry all night, and about 2% it can take until puberty.
Good luck mama. This is still the easy stuff - it gets more tough as the years go by - but the rewards increase too. ;o)
