Looking for advice / opinions on switching my bedroom and office

I'm going to be a FTM in February and I live in a 2 bedroom duplex apartment. Right now, our bedroom is on the top floor (half floor with just a bathroom and a laundry closet) next to it. I work from home most of the time and my office is on the main floor next to the kitchen, another bathroom and the living room. My husband and I are both photographers and we have a ton of stuff in the office. Both the bedroom and office are the same size rooms. The baby is going to have to sleep in our bedroom for the foreseeable future, and I decided I want to switch the bedroom to downstairs so that we won't have to constantly carry the baby up and down more stairs than necessary (middle of the night, etc). We also have to go up 2 flights of stairs just to get into the main level of our apt. And I think all our stairs are unusually steep.

Now I'm questioning this plan because my neighbor was saying that we'll have to be especially quiet in the kitchen / living room whenever the baby is sleeping. But I also keep thinking about my friend's 18 month old baby boy who weighs a ton, and carrying him up and down all of those stairs.

I know this isn't a product question per se, but I have follow up questions about that too 😊. What do you think? Thanks!
