S.O.
Hi R.!
I have less advice for you & more just some reassurance that you aren't alone! I have 3 children. My 9 yr old girl & 7 yr old boy were both potty trained by age 2 - no problems w/either. BUT - I have a son who just turned 3 August 8th. He is STILL not potty trained.
Methods we've tried include: Singing a family "Teetee in the Potty" song & dance each time, a sticker rewards chart, having him aim @ Cheerios, naked days (he likes those - but they didn't help w/potty training - we had LOTS of accidents in his room wherever he happened to be playing) & bribing him w/treats (such as an M&M) each time he went.
We've also taken him to the store to pick out his own "big boy underwear" just like Daddy's & Big Brother's. (It's sitting in his drawer - accidents TOO MESSY & TOO FREQUENT!)
He's smart, strong-willed & the advice I received is that this is simply a power struggle. SO: We informed him that there will be no more stickers, candy, songs, etc ... that his Big Boy Underwear is in his drawer & that when he's ready he can use it!
My birthday was Oct. 3rd - he went potty ALL DAY & said "Happy Birthday Mama!" each time! However, from then on it's back to diapers!!!
I just wish you the best of luck & - if anyone's advice helps you - PLEASE post a follow-up ... maybe it'll be something I haven't thought of! (ha)
Remember, though, that all kids train on their own schedule. I CONSIDERED going back to work this year & looked @ some preschools. The one we liked had a WAITING LIST for the 3 year old NON-Potty Trained room, but openings in the 3 year old Potty Trained room. That should tell you that you aren't alone in this!
