~Potty Training Dilemma!

Well, three or four weeks ago I made the mistake of running very low on diapers.  I was planning on going to Wal-Mart, but not for two days.  So, I decided to pull out the training pants and let Miss Felicity wear them during the day and at night we would use the diapers we had on hand.  This was a BIG mistake!!  Miss Felicity does not like to wear her diapers anymore.  She realizes how much softer her new panties are!  Sounds like a good thing, right? Esp. since diapers are so very expensive. Well, you see, the problem we have is she Felicity refuses to sit on the potty! She cries, stiffens her legs up so I cannot even try to make her sit there.  This is my fourth baby to potty train, we have never had this issue! What am I going to do?!?  Any suggestions!!! We even had Kylie's pink training potty out for awhile, she would carry it around, but absolutely no sitting!  Help!!!!!

Anyhow, she does look super cute in her Big Girl Pants!  I loved this photo in black and white and in color! Which do you like best?!?!
