It's actually VERY common for 3, 4 and sometimes 5 and 6 year olds to NOT want to stop their activity to go to the bathroom. My youngest took forever to stop what she's doing to go to the potty. I finally had to use a reward system with stickers because she loved stickers: Sit on the potty for 5 minutes, and if you go, you put a sticker in the smiley face column. If you don't go but you sat there for 5 minutes, you put a sticker on the "I tried!" column. During that five minutes, she had to sit on the potty and I would read a story or sing a song with her to pass the time. I also turned the faucet on to "inspire" the flow. LOL
The way I look at it is that sometime before she is married, she'll use the potty all the time, not wet the bed, and give up the pacifier (or thumb sucking). Until then, I'm not too worried about how she compares to other kids her age as far as development goes. :)
Hope that helps!
