My rabbits have free roam in my bedroom, in its entirety, and let them out into the main house after work. Because we have far too many predators in area (hawks, dogs, cats), I can't keep them outdoors. It took me a minute to tell my mother-in-law to not waste money on an outdoor hutch because of that very reason. I don't know how it is where you live, but as long as your baby is safe and happy, I don't think you should feel guilty doing it. You're giving her fresh air and somewhere else to be for a while.
Edit: As a lot of us know, rabbits tend to be curious when they enter a new area. lol
