Preparing cats for baby

Has anyone had an issue with their cats before baby came?

We have two cats, and while they can sense something is changing, only one of them is really acting up.

She’s our older one, about 3 years old. She’s been scratching the HELL out of our couches (no she’s no declawed and I’m not going to declaw her), sitting in the stairwell by our front door and doing that low, long meow that they usually do after they kill something outside (she’s an indoor cat, and my husband and I call them her ‘murder screams’), and she’s just getting into everything!!

She’s my first baby and I love her and want to help her adjust, but it’s getting very frustrating😭

I’m also worried about the nursery, currently it’s our guest bedroom and the cats sleep on that guest bed, I don’t want to rock their world when I remove the bed and basically kick them out of the room
