Congrats Alice!!!
Boy that is exciting - many many congrats!!!
I would leave her be - last season when I did my first clutch MI style I was in and out of the tub all the time changed the substrate, checked and candled eggs, etc. and Mom was fine with it when I was done she went right back to sitting on them they all hatched out perfect.
This year my first clutch hit the ground and everything was going smoothly for two weeks - then one day mom got off the eggs and never went back on them. First time jitters aside - I was for the most part just leaving her to her duties and can't pinpoint anything in particular that was done that would make her not want to sit on the eggs. But it happened - maybe she just wasn't the maternal type. Maybe it was temperment - so I would recommend just leaving her where she is just to be on the safe side.
She may leave them to get something to drink or adjust her self occassionally - if so you can take a peak at the eggs and see how they are doing.
Hope it helps -
