Potty mouth

Since today marks the beginning of 10 days of vacation from my nanny job, I decided to see if Marissa was ready for potty training. I didn't want to have to worry about the kids I watch, and I didn't want to have to train Marissa AND the little boy at the same time, since I have no clue what I'm doing. So this is really the ideal time. She used to seem so ready, way back in July (when I was miserably "morning sick"), so I figured she'd be even more ready now.

But...

today she seems clueless. We slept til 9am (which was a miracle, since I went to bed at 9:45 with a migraine last night), and she's been in undies since then. Dora undies even. But she already soaked one pair, pooped in another pair, and has only dribbled one time in the potty (which she promptly received an M&M for). I've had her sit down and try about every 10-15 minutes, but she hasn't gone at all. Shouldn't she have to pee more than once in the morning? Lol. I keep trying to get her to drink more juice, but everyone knows you can't really force a 2-year old to do much of anything

So...help? Tips? Advice? What to do differently? What NOT to do? Anybody? If she doesn't start to really get it over the weekend, we'll wait and try again later. But I just want to get this over with!
