Stubborn

Well, I think Faith may be a little stubborn. We have left her diaper off all day for the last 3 days (only putting it on for bed time and snacks, and of course when we leave the house which has only been once.) She's only gone in the potty chair that one time and I think it was because she was afraid to get off with the vaccum going. Otherwise she hasn't even had an accident. (Except for when Daddy got her in trouble for trying to go outside for the hundredth time today.) Her diaper will be off for 4 hours at a time and nothing. I know she has to go because she'll grab herself and tell me potty, but won't go when she sits on the potty chair. When we put her diaper on for a meal (It's on for no more than 20 min.) it will be soaked!! The little stinker just waits for us to put her diaper on to go potty.
A funny side note, Faith and I were sitting on the couch (She was sitting on a towel), Faith was snacking on some crackers and I was cross-stitching. All the sudden Faith got red in the face and started grunting and a few toots came out. I thought "OH HEAVENS!! She's pooping on the couch!!" But she just started laughing and that was the end, just a scare. But I wonder if she's holding that in too?
So now I'm thinking about getting her some big girl panties to wear around the house. She might go in them because there's something on and then realize it's not so fun, leaving the only option being going in the potty chair. She'll sit on the potty chair and read her books, I just don't understand why she won't use it to go potty. Oh, well. Just keep trying I quess.
