Our first night trying "Big Girl Panties"

So Bailey is giving us signs that she wants to start potty training. One of our favorite ticks from Bailey is the hand full of poop and then she tries to clean it herself, what a big girl.....ugh....and gross! I would rather give birth 10 times over than deal with potty training. I need suggestions and lots of tip so feel free to inform me....! So tonight she got to wear big girl panties and has gone through both pairs I bought her. thank goodness it's close to bedtime and the diaper could go back on. In her defense she did really good going in the toilet. So I need help!!!!!!!!!!
