We have 2 girls that both potty trained around 2 and 1/2. Our older daughter wore cloth diapers for the first 6 months. We never did it with the second. Anyway, in both cases, we went straight from diapers to the gerber training pants. We bought the plastic covers for our second daughter, but haven't really used them. In general, we just do a lot of laundry and do a lot of reminding about the potty. We've had to make potty part of our routine to help her be successful.
We use the pull-ups at night and on trips. We occassionally use them on days when we've had a lot of accidents.
Good luck. Either way, you're going to have pee pee to deal with until she's at least past 3. It's hard to be patient through it all.
