Why yes I do.
My now 16 year old wasn't potty trained until she was 3. I thought it was going to be EXPENSIVE having two in diapers. Once we brought baby home, it wasn't but maybe a week before she got it. Consistency, sticker method, and outward forgiveness when mistakes happened.
My now 13 year old son was the same. He, too was trained by 3.
My 3 year old, (adopted from Vietnam) has had some much trauma in the first 2 1/2 years of his life and wasn't introduced to food even until he was over a year is a bit more challenging. We are not pushing him to get it right away because there hasn't been a whole lot of stability which in some children have issues with potty when that happens. Today actually is the first day he got to wear "big boy underpants" rather than a pull up. He has not had one accident today. Again, consistency is a huge part.
Still having trouble explaining the rules to my almost 14 month old, but when it is time, it will be the same. LOL..
A child who shows interest is the best time for parent(s) become consistently interested in teaching. There is nothing wrong with introducing the idea around age 2 or when they can verbally communicate potty in toilet talk. Doctors for some reason want children off the bottle/breastfeeding and potty trained early which is frustrating.
Anyway, there's my few cents
