I started training my daughter around 16 months. She was fully trained (including nighttime) around 21/22 months. It will be a lot of work, but I say go for it now! I clothed diapered, so yes cloth diaper! The more she can feel it, the better!
When she is getting about 80% of it in the toilet, put her in trainers --with no covers. The Gerbers work great. Save the big girl undies for something special. We used them to get my daughter to go poop in the toilet. When she would do that, she got her Elmos. She then wanted them at night time, so we told her she had to wake dry 5 nights in a row to wear her elmos to bed. Do make sure you put her in cloth at night-time! No pull-ups!
It's important to put her on a schedule and teach her what I call "potty etiquette," you go when you get up, after breakfast, before leaving the house, etc. She will get distracted for a long time coming. My daughter is 30 months and we still have accidents (mind you, her accidents are barely wetting her pants and getting herself to the toilet to go, but she still gets distracted and thinks she can keep holding it!)
Let me add a few things: when you start early, you finish earlier. So, even if there are regressions (my daughter had a few, when her brother was born, when I went away for a few days), these regressions are happening when their peers haven't even started! So, ignore the Na-sayers, and get busy! Prior to 1960, 80% of all kids were trained before 18 months. The rest of the world trains before 2, it's only us Pamper loving Americans who like their toddlers and little kids to run around with poop in their pants!
Also, look at helping her to potty as you looked at helping her to walk. They need help, yes, but this doesn't mean they aren't capable. If they are able to distinguish between wet and dry, are aware of the sensations and pressure, they are ready. Just keep talking it all up (do you feel pressure in your bottom? do you feel pressure, like you need to pee). In short, just because you have to help them with their pants and wiping, etc. it doesn't mean they can't do it. Most have the control and ability, we are just lazy. Could you imagine a mom saying "no, i won't hold your hand while you learn to walk?" Unthinkable, yet, taking a kid's pants off to help them go pee is?!
ALL kids show a window of interest before 2. TAKE IT AND RUN. They get so oppositional after they turn 2! (as I am sure you know).
