I've read the "signs" if they're ready, and DD gets almost all of them (she can't completely pull her pants on/off). But how did you know LO was REALLY ready for potty training?

DD is 25 months, tells me when she's pooped, knows what the potty is for, and can go a few hours without peeing. I was thinking about trying to train her over the 4th of July weekend, but she hasn't told me she wants to train, so I guess I'm not sure she's ready?
