I'm a parent of a fully potty trained 24 month old. Mostly potty trained by 18 months, with lots of reminders. It's not easy, takes absolute commitment. The moment you look at your phone your 16-18 month old will be hiding behind then couch peeing (at least ours did). That being said, it's nearly impossible if you don't have a parent doing full time caregiving. No daycare will do it. My wife used to do it as a nanny, where she learned about it, but that's an outlier. Really not easy to navigate between you and your family or friends who have similar age kids!
