Potty Training

Eeeekk... I have been terrified of potty training ever since the other toddlers started using the potty. It seemed like it was going to be an extremely time consuming, messy and frustrating process. So we have been starting very slowly with Kate. I was secretly hoping that one day we would wake and up and she would magically start telling me when she had to go potty. Umm, yea right. Back to reality. After a couple of months of practice, she has nearly mastered "pooping on the paawty" (oh the terminology of potty training). Now we are moving to "peeing on the paawty". I really don't know how to approach this. Kate gets so annoyed if I keep asking her if she needs to go potty. I tried putting her in underwear one morning and sat her down on a "magic carpet" (very thick towel) to watch Aladdin. This tactic ended less than an hour later with a big wet mess. How can I get Kate to like using the potty? I think the next tactic will be humor. How about if I let her wear underwear on her head whenever she uses the potty? I'll let you know how it goes.
