I gave my son 2 M&M's every time he went on the potty. It worked. Summer time is a great time to potty train...just let her run around with no pants on. Keep a potty near by (if you're outside or in the living room). I have also heard parents will use a timer and ever 1.5 hours have the child sit on the potty. I wouldn't force her to sit there if she doesn't have to go (then it becomes a negative thing). Just make sure to do the super happy potty dance whenever she successfully goes in the potty. GOod luck!
