There really are huge myths about potty training and of course, every child is different. I'm always amazed at how they are, allegedly, supposed to be trained at an exact age when nobody expects children to walk, speak or reach any other developmental milestones at precisely the same moment.
When ds1 was nearly a year old, my MIL and her vile and silly sister assured me that he'd be going to school in nappies if I didn't get on with PT him. Apparently, all their children were reliably out of nappies long before they could walk. But then they were from the generation who fooled themselves that holding a baby over a potty and catching the inevitable, if occasional wee, constituted any sort of training.
ds1 had a summer birthday. At just after 2 he showed signs of being ready to be trained so I had a go. Most of the accidents occurred, helpfully, in the garden because the weather was warm and being a rather precise sort of child, he was quite quick to catch on so yes, by 2.3 he was trained. This fluke was not repeated when I attempted it on ds2 who was much nearer 2.8 and even then not averse to accidents because he was much less bothered.
dgd is nearly 2. She's bright and very verbal. But she's not ready to be potty trained now and I very much doubt she will be in 6 weeks time. So don't go by age, go by instinct and knowing your own child.
