We didn't potty train until ours was over 3 (3 years, 3 months). She is super smart and verbal, but struggled understanding and "listening" to her body. She was a little late with crawling, walking, and is a total clutz. I really think that had EVERYTHING to do with it.
We chose a weekend we'd be home (almost a year ago), and set the timer for every 15 minutes. ADD: Make sure you give her lots to drink all day long!!!!
I made a Dora chart with a picture of a Dora backpack she would get after 12 successful potties. I gave her an M&M for trying and 2 more if she peed. I had her sit on a towel without any underwear on, on the couch and watch tv (a super treat). By the time she got on the potty, tried, washed her hands and I reset the time, 25 - 30 minutes had gone by.
Once we finally got the ball rolling and got some pee in that potty (and it made music!!!), we made serious progress. By the 2nd night we went to Target to get her backpack. She never wore a diaper again and only wore pull-ups during long car rides and overnight (she gave up napping at 2). Honestly, she still wears pull-ups at night and only until a week ago started waking up dry in the mornings. We are getting ready to do night training.
She did not poop train for several months. That took going to preschool. She only goes two mornings a week, but that made all the difference of her independence, too. We used to have to help every single time. Now, she goes on her own. (YAY!!!!!!!)
I liked getting her the backpack for an incentive. We carried extra clothes in it, a portable fold-up potty for large potties, wipes, and hand sanitizer. She was so proud to take her bag with her and I didn't have to put all of that stuff in my bag. :) Good luck mama. Just start it, be positive, give incentives, and be consistent.
