Maybe I'm the only one, but when I reduced the pressure (a/k/a gave up) DD3 advanced, and when I got excited about her progress and tried to push her toward the next level she regressed. Long story short, she was fully (night & day) potty trained by the time she was 2 1/2. My belief is that if I had let go sooner she'd have been done sooner, and if I'd pushed harder she'd still be wearing diapers.
That said, she showed interest in potty training from a very early age. Perhaps if that is not the case for your child, more intensive potty training is necessary. I don't know. Anyway, good luck.
