Potty Training.. Round 2

We made an attempt at potty training Hannah back in February... and it wasn't a success. We opted to not make it a battle & wait a bit longer. We still left up the potty charts & we even asked if she needed to go before putting her in the bath, & she would go every now & then. While we were in SLC she took more of an interest & used the potty often. It was very helpful to have all of her cousins around & they are all potty trained. I still didn't really push the issue, I would ask if she wanted to still wear diapers & she said she was going to wear panties when we got home. She changed her mind by the time we got home, of course!
Yesterday was an annoying diaper day. Every time Hannah peed she wanted her bum changed! We went through way too many diapers. So this morning I was changing her & opened the diaper drawer to find that it needed to be restocked. I told her there were no diapers in there & asked what we should do (assuming she would say to go find some in the cupboard or go buy some at the store.) Well she shocked me by saying she would wear panties & she ran to her room & got a pair. She did great this morning! She would go in & go before I got around to asking.
She did have one accident, that was partially my fault. We were outside playing & I went in to put Milo down for his nap & forgot to get her to go potty. I had heard what sounded like her yelling, so I came out to see that she was playing just fine, so I went back to getting Milo down. When I came back out she had found a can of bug spray so I quickly informed her that wasn't something she should play with, & noticed she had it all over her & she had washed her little car with it. I told her we were going to need to take a bath. When I bent down, I placed my hand on her bum to find it wet. I asked if she had an accident, she said she yelled for me but I didn't come. She then told me not to worry, she covered it up so I wouldn't step in it! (Isn't she sweet?!) This afternoon she even went Home Depot with Jeff & didn't have an accident. Jeff is really thinking this is it, I'm not getting my hopes up because it's only day #1. We have had day 1 before, but I know we are making progress, & that's all that matters. Hannah is a lot like me & I know that potty training is going to be a control thing & I will wait & make sure it is on her terms & in her control, otherwise she will pee her pants just to prove a point or because she's mad at me.
