Convo with Olivia

*as Im changing her morning diaper* Olivia: No thankyou Me: Olivia mommy needs to get your diaper on Olivia: No thankyou Me: Do you want to wear your Elmo panties? Olivia: Well OK then, yes please Mommy Me: if you wear your Elmo panties you have to go pee in the potty Olivia: Diaper please ME: wouldnt you like to wear your Elmo panties? Olivia: No thankyou FTR she has never had an accident in her panties, ever. She was doing so great in her BGU that she was almost completely out of day time diapers. Then out of nowhere she started asking for a diaper when she had to go to the bathroom, she would get a diaper on pee in it then take it off herself and put her underwear back on. Im assuming this is a normal part of the process. I am in no hurry atall to get her 'potty trained' Im just wondering WHY she has this sudden adversion to going on her potty?
