If you can swing it I'd move out.
Construction is messy. Tools are dangerous.
It'll take a lot of time for the crew to pack up everything every night. I'd prefer they use that time working.
We've lived through some big projects with one kid and it sucked.
Not having a kitchen or bathrooms is bad enough, but having dust over everything literally everything was my breaking point.

I have a friend who was in a similar situation and they elected to stay for the bulk. It took about 6 months to finish everything and they left a few times, a week once or twice and a few couple of day periods. They used heavy plastic over the doorways and even put up a fake plywood wall in one place to keep the dust out. They moved the fridge, coffee maker, a water dispenser, a microwave and a hot plate to the living room and set up a make shift kitchen. I believe she got an air filter too. They left when it was going to be especially loud or when there would be anything smelly/toxic like when the floors were being refinished.

In their case the bathrooms weren't being done at the same time, they did the kitchen, dining room, basement and roof at once and then a year later did the bathrooms. Her mom had plenty of room for them and lives pretty close but too far for school which was tricky.

I would budget for 6 months in an inexpensive rental as part of costs. Things always take longer and cost more so I'd rather have that in the plan to start with as it sounds like it's gonna be a lot of your home!

I vote move out. I feel like it would be too stressful and possibly take longer to get things done with a family in the way.

MOVE OUT! We are currently renovating our 2 bathrooms (1 at a time) and, knock wood, the renovation is on schedule, but it's still kind of a nightmare. We still have access to our kitchen, living room, playroom, and both bedrooms, but just having the paper down, tools in the foyer, and dining room all covered with plastic is stressing me out. It's freezing here and I still have to find out of the house activities for us to do every morning and afternoon.

If there is a way you can move out for at least the kitchen and baths, and then stay in another bedroom while the master bath/loft is being done, that could be a compromise.
