Hi K.,
Its great that your baby is learning about her body and communicating about it too. However, many babies this age are able to recognize that they have a dirty diaper and let a parent know. It doesn't mean that they are ready to use the ttoilet, or to tell you that they have to - often telling that they have to go is the last step in the process, not a first step. Both of my kids had told me they'd already gone for a year and a half before training.
Most 17 month olds aren't ready to train. Often when parents start at this age, the process takes a long time, months (or more). I didn't opt for this since I didn't enjoy the process, find it cute or anything - I found it easier to have kids in diapers than ones who would use the toilet occasionally, have lots of accidents, etc.
However, when your daughter shows signs of readiness - staying dry for a few hours at a time, able to take her own pants up and down, maybe the awareness that she is urinating, I'd say to use cloth diapers or cloth training pants with waterproof outer layer/plastic pants. This lets her know what happens when she pees - she gets very wet, and starts to recognize what it feels like just before that happens. Disposable products don't allow for that wetness. Take her to the toilet frequently - I did it every hour and a half. Don't ask if she has to or wants to, simply take her. It took my son 2-3 weeks to stop going in the cloth training pants and to wait til the toilet trips to go, but he did. However, it was still a month after that before he started to verbalize the need to use the bathroom. That's often a late step. And while it could go either way, many kids are pee trained before poo trained. Although my kids were both at once. Good luck!
