Update on potty training

Kali has been WAY harder than Anna.  She still has accidents and she still needs lots of encouragement.  I feel like she is just on the edge of being completely successful but she just needs an extra push...not sure what to do.  We have tried to be really encouraging but man sometimes I just want to scream.  She pushes all my sanity buttons.  This means that all this hard work is for what?  Well I just hope and pray that all that we've tried to teach her will stick when the baby comes.  Starting completely over just sounds terrible but that may be what ends up happening.
