The Adventures of Potty Training

We've made a few attempts at getting Skylee potty trained but this time, we're serious! We've been consistant for the past week and a half now, and I feel like I'm the one potty trained. I'm trained on the hour to take her to her potty, she goes, we celebrate...I've taken a lot of advice from different moms, but I'm feeling pretty stuck right now. Skylee is at a point where she knows what to do, but doesn't get that it's not my responsibility to get her to the potty in time. She has no problem doing it, but only if we're the ones that tell her to. I'm just wondering how and when she will catch on to doing it all by herself? Is that something that just comes with time, or is there a trick? I know Skylee is just barely 2 years old, and some may say that's too young, but she's so smart and since we've been doing it, she knows the drill. I know we're at a point now that we can't stop what we've started or it will just make it harder next time, so I need some suggestions! This is what we do so you know how to critique: (She wears underwear all day long, at naps, but diapers at bedtime. Most of the time when her diaper is on she'll still tell me that she went to the bathroom)

Creating Success:

*Every hour take her to her potty

*She goes

*We make a big deal, celebrate

*She gets a treat

When Accidents Happen:

*She comes to tell us "I went pee pee in my underwears! Oh no, that's yucky!"

*In the best and most simple way we know how, we tell her that big girls don't go potty in their underwear, they go potty on the toilet. We try to explain that she has to tell us when she needs to go, not to go in her underwear.

*We quickly change her clothes and tell her not to go potty in her nice clean ones.

What am I doing wrong??? I ordered a DVD for Skylee to watch about big girls saying bye to diapers and using the potty, just got it in the mail, so we'll be watching it after her nap today!
