IMO, between 18months- 2 1/2yrs is the perfect time to Introduce kids to the potty. put them on there every now and then. like if you see the look on their face, or the signs that you know means they're about to poop, if they let you, run them over to the potty, sit with them and read a book, sing songs until they're done. it's ok if they've already went a little in their diaper, it's just and introduction. don't force them, if they don't want to, they don't have to. and it does't have to be all the time either. IMO, at 2 1/2 is when you start cracking down more, if it's any earlier it's only cuz your positive they are completely ready.
it's very frustrating, the resolve was my best friend the week i cracked down on my son. but i had him in underwear during the day in 4 days :) dd will be 2 tomorrow, i've already started introducing, this winter is when i'll start cracking down. GL
