I have 4 kids and all of them hard their own way of potty training.

I have also been a toddler teacher...so I have potty trained a lot of children.
I would suggest:
*Setting a time to potty train her. Pick a week that you can 'stay home' and with potty.
* Make 'potty training' seem like a " big deal"...something she should be very excited about.
*I think it is very confusing to children to go back and forth between panties and diapers during the day. Tell her she is a big girl and big girls only wear 'big girl panties'. Then no matter what don't go back. A diaper at night is okay until she has outgrown wetting at night. Once my girls were potty trained during the day...they also stayed dry at night.
* I would start out... taking her "potty" every couple of hours. Once she gets it you can space out the trips to the potty.
*Pick something that she loves more then anything else in the world. Use this as your item to bribe her with. She can only have this item if she goes potty she can have this special item. It might be tv time, a special toy, trip to the park, play time outside.
*When my kids went pee in the toilet we would call grandma and she would "gush with excitement over it". This helped! We would also call her aunt too.
* When I started potty training I would give my kids a skittles (2 with nut allergies too). Once they figured out how to go "pee" in the potty.
--I changed to earning a "trip to krispie creme for a donut"... if they
stayed dry for 1 day.
--Then moved to, if you stay dry for 5 day... you can get to go out to
ice cream with daddy.
--After 10 days of this, we went to if you do not have accident for one
week we will buy you ? or take you somewhere.
* Potty training is something they have total contol over. But that doesn't mean we can bribe them to do what we want.
*Never make it a power struggle. Take her potty if she doesn't pee move on. Try again in a little while. You can also just send her to go potty on her own.
Good luck!
