Just a couple things that worked well for us -
A) Let her take the lead with whether she wants to go potty - have her around others going potty, talk about what big girls they are (sister, friends etc) get some books about going without diapers etc., and while you are taking some time off the training, read those and talk about it, but without much reference to her and no pressure to do it - mainly reference to her friends and the characters in the book. Remember that motivation doesn't come from nowhere - you need to plant the seed a little bit sometimes in a gentle way.
B) when you decide to start again and she has an accident, say 'let's see if there's anything else coming and sit on the potty' (prob a potty is better than big toilet at first). They have more control with a potty and can learn to do it all themselves - take clothes off and sit on it with virtually no help, and quite quickly. The reason sitting on the potty immediately after the accident works, is due to the association they have with peeing and then sitting on the potty - makes the learning easier/quicker. Also, then you have a task to focus on, rather than getting upset which leads me to
C) never scold or get angry about accidents, just calmly take her to the potty to 'see if anything else wants to come out'
You can look up Dr Phil for a more extreme form of this (which is where I got the idea). Personally, I don't think its realistic to expect them to sit on the potty 10 times after each accident as he suggests. It seems more like a punishment that way to me. Just the one time seemed to work really well for us - took less than a week for no more accidents.
Good luck!
