I'm so happy about this! Now, I can use the money we won't be spending on diapers for Katie to start stocking up on diapers for the new baby. And since it will be months before the new baby is here, there shouldn't be any regressing for Katie because she'll be so far past the diaper stage.
Here's a pic I took of Katie last night dancing around in her panties and Daddy's boots. Sorry if it's a little blurry.
