I wouldn't move the brake levers at all if it were my bike. The rule of thumb I was always taught, and what has always worked for me, is that a straight-edge run along the bottom of the handlebar drops should touch the bottom tip of the brake lever, and it looks like she's right there as it is. Obviously personal taste and comfort issues require tweaking from that point if necessary, but moving the brake levers would be at the very bottom of my list of any needed adjustments. Rotate the bars, absolutely, but leave the brake levers where they are.

Oh, and welcome, Lucille!
